In the 1990s, as other investigators, I was particularly concerned about the high risk of relapse in depression and its link with residual symptomatology [1]. It was not easy to make the patients better, but it was even more difficult to keep them well. My co-workers and I had performed a small controlled study on the effects of addressing residual symptomatology with cognitive-behavior therapy (CBT) in reducing relapse rates. Compared with a control condition, there were significant differences after 4 years [2], but not after 6 years [3]. I felt that what I had introduced (a sequential strategy: first treatment with antidepressant drugs and then CBT of residual symptoms) was good, but it was not sufficient.
I was looking for a psychotherapeutic strategy that could increase the level of recovery. This was the setting where I developed a psychotherapeutic technique for increasing psychological well-being, well-being therapy (WBT) [4]. Since CBT of residual symptoms of depression was found to be more effective than clinical management [5], I thought that comparing the two strategies (CBT and WBT) could be the first step. Twenty patients with mood and anxiety disorders who had been successfully treated by behavioral (anxiety disorders) or pharmacological (mood disorders) methods were randomly assigned to either WBT or CBT of residual symptoms [6]. Both WBT and CBT were associated with a significant reduction of residual symptoms, as measured by the Clinical Interview for Depression (CID) [7], and increases in well-being, as assessed by the Psychological Well-Being (PWB) scales [8]. However, when residual symptoms of the two groups were compared after treatment, a significant advantage of WBT over CBT was observed with the CID. WBT was also associated with a significant increase in PWB, particularly in the personal growth scale [6]. The small number of subjects suggested caution in interpreting this difference and the need for further studies with larger samples of patients with specific mood or anxiety disorders.
This is why I decided to include WBT in the treatment package, together with CBT of residual symptoms and lifestyle modification, of a study concerned with patients with a severe form of recurrent depression defined as the occurrence of 3 or more episodes of unipolar depression, with the immediately preceding episode being no more than 2.5 years before the onset of the current episode [9]. Forty patients with recurrent major depression, who had been successfully treated with antidepressant drugs, were randomly assigned to either this package including WBT or clinical management. In clinical management the same number of sessions that was used in the experimental condition was given. Clinical management consisted of reviewing the clinical status of the patient and providing the patient with support and advice, if necessary. In both groups, antidepressant drugs were tapered and discontinued. The group that received CBT and WBT had a significantly lower level of residual symptoms after drug discontinuation in comparison with the clinical management group. CBT also resulted in a significantly lower relapse rate (25%) at a 2-year follow-up than did clinical management (80%). At a 6-year follow-up [10], the relapse rate was 40% in the former group and 90% in the latter. Further, the group treated with CBT and WBT had a significantly lower number of recurrences when multiple relapses were taken into account. Even though it was a small and preliminary study, the results were quite impressive: more than half of the patients treated with CBT and WBT were well and drug free at a 6-year follow-up [10].
The findings were replicated by three independent studies. In a multi-center trial performed in Germany, 180 patients with 3 or more episodes of major depression were randomized to a combination of CBT, WBT and mindfulness-based cognitive therapy or to manualized psychoeducation [11]. Even though the follow-up was limited to 1 year (in our study the most substantial differences emerged later) and medication was continued, there was a significant effect of the experimental condition on the relapse rate of the patients with high risk of recurrence.
In the USA, Kennard et al. [12] applied the sequential treatment we had introduced in adults [9] to 144 children and adolescents with major depression. They were treated with fluoxetine for 6 weeks, and those who displayed an adequate response were randomized to receive either continued medication management or CBT to address residual symptoms and WBT in addition to fluoxetine. The CBT/WBT combination was effective in reducing the risk of relapse, a finding that was quite exceptional in the literature concerned with children and adolescents with major depression. Unfortunately, unlike our original study [9], medication was also continued in the CBT/WBT group, despite the problems that are related to long-term treatment with antidepressant drugs in that patient population [13].
A third confirmation came from Iran in a study by Moeenizadeh and Salagame [14]. Forty high-school and university students suffering from depression were randomly assigned to WBT or CBT. The results unequivocally showed that WBT was more effective than CBT in improving symptoms of depression [14]. The severity of the depressive disturbances was not specifically evaluated and the symptomatology was probably mild. Nonetheless, the results were quite impressive.
In the course of the years WBT gained from the insights that derived from its application to other disorders [15]. The original protocol [4] underwent a first modification in 2009 [15] and was eventually finalized in a treatment manual [16]. I will outline the main technical characteristics and aims of WBT, its currents areas of application and some emerging perspectives.
The Structure
WBT is a short-term psychotherapeutic strategy that emphasizes self-observation, with the use of a structured diary, interaction between patients and therapists and homework. WBT is based on a model of psychological well-being that was originally developed by Marie Jahoda in 1958 [17]. She outlined 6 criteria for positive mental health: autonomy (regulation of behavior from within), environmental mastery, satisfactory interactions with other people and the milieu, the individual's style and degree of growth, development or self-actualization, the attitudes of an individual toward his/her own self (self-perception/acceptance) and the individual's balance and integration of psychic forces. Carol Ryff further elaborated the first 5 dimensions of positive functioning and introduced a method for their assessment, the PWB scales [7]. While initially WBT was simply aimed at increasing psychological well-being, its goal was subsequently refined in the achievement of a state of euthymia, Jahoda's sixth criterion [17]. She defined it as the individual's balance of psychic forces (flexibility), a unifying outlook on life which guides actions and feelings for shaping the future accordingly, and resistance to stress (resilience and anxiety or frustration tolerance). It is not simply generic (and clinically useless) advice of avoiding excesses and extremes; it is how the individual adjusts the psychological dimensions of well-being to changing needs [18].
Articulation
WBT may be used as the only therapeutic strategy. In this case the number of sessions may range from 8 to 16-20. The duration of each session may range from 45 to 60 min. WBT may also be used in sequential combination with other psychotherapeutic strategies, in particular CBT, and in this case the number of sessions may be abridged to 4-6 [16]. The sequential combination of CBT/WBT has characterized its use so far [16].
The initial phase is concerned with self-observation of psychological well-being. Once the instances of well-being are properly recognized, the patient is encouraged to identify thoughts, beliefs and behaviors leading to premature interruption of well-being (intermediate phase). The final part involves cognitive restructuring of dysfunctional dimensions of psychological well-being and meeting the challenge that optimal experiences may entail [16].
WBT was originally conceived as an individual therapy [4], but it may be amenable to a group format [14]. This modality may increase sharing optimal experiences and personal meanings of psychological well-being. It is also conceivable, even though yet to be tested, that WBT interventions may increase the effectiveness of couple and family interventions. Kauffman and Silberman [19] have illustrated adaptations of positive psychology interventions that may improve the outcomes of couple therapy. Fostering the positive in relationships is indeed a target of many family and couple approaches and elements of WBT may facilitate such a process.
An additional modality for WBT involves the growing area of computer-assisted methods. Treatment programs or mobile applications could help clinicians and reach a wider audience.
Characteristic Features
Within the broad and highly heterogeneous spectrum of positive interventions [20], WBT stands for some specific aspects:
Monitoring of Psychological Well-Being in a Diary. Patients are encouraged to identify episodes of well-being and to set them into a situational context. They are asked to report in a structured diary the circumstances surrounding their episodes of well-being, rated on a scale of 0-100, with 0 being absence of well-being and 100 the most intense well-being that could be experienced. Such a search also involves optimal experiences. These are characterized by the perception of high environmental challenges and environmental mastery, deep concentration, involvement, enjoyment, control of the situation, clear feedback on the course of activity and intrinsic motivation [21].
Identification of Low Tolerance to Well-Being by Seeking Automatic Thoughts. Once the instances of well-being are properly recognized, the patient is encouraged to identify thoughts and beliefs leading to premature interruption of well-being (automatic thoughts), as is performed in cognitive therapy [22]. The trigger for self-observation is, however, different, being based on well-being instead of distress, as illustrated in figures 1 and 2.
Behavioral Exposure. The therapist may also reinforce and encourage activities that are likely to elicit well-being and optimal experiences (for instance, assigning the task of undertaking particular pleasurable activities for a certain time each day). Such reinforcement may also result in graded task assignments [22], with special reference to exposure to feared or challenging situations which the patient is likely to avoid. Meeting the challenge that optimal experiences may entail is emphasized, because it is through this challenge that growth and improvement of self can take place.
Cognitive Restructuring Using Specific Psychological Well-Being Models. The monitoring of the course of episodes of well-being allows the therapist to realize specific impairments or excessive levels in well-being dimensions according to the conceptual framework of Jahoda [17] and Ryff [7]. For example, the therapist could explain that autonomy consists of possessing an internal locus of control, independence and self-determination, or that personal growth consists of being open to new experiences and considering the self as expanding over time, if the patient's attitudes show impairments in these specific areas. The patient thus becomes able to readily identify moments of well-being, be aware of interruptions to well-being feelings (cognitions), utilize cognitive behavioral techniques to address these interruptions and pursue optimal experiences.
Individualized and Balanced Focus. Patients are not simply encouraged to pursue the highest possible levels in psychological well-being in all dimensions, as is found to be the case in most positive interventions [20], but to obtain a balanced functioning, subsumed under the rubric of euthymia [18]. Positive characteristics such as gratitude and autonomy often exist on a continuum [23]. They are neither ‘negative' nor ‘positive': their impact depends on the specific situation and on the interaction with concurrent distress and other psychological attitudes. This optimal-balanced well-being could be different from patient to patient, according to factors such as personality traits, social roles and cultural and social contexts.
Current Indications
WBT has been tested in a number of controlled trials, mostly as an adjunctive treatment ingredient. Unlike many other psychotherapeutic strategies, it was not conceived as a cure for mental disorders, but as a therapeutic tool to be incorporated in a therapeutic plan. As a general indication, it is difficult to apply WBT as the first-line treatment of an acute psychiatric disorder. It may be more suitable for second- or third-line treatments. Most of the patients who are seen in clinical practice have complex and chronic disorders [24]. It is simply wishful thinking to believe that one course of treatment will be sufficient for yielding lasting and satisfactory remission. Further, WBT was not conceived to be used in every patient who meets specific diagnostic criteria [16]. It should follow clinical reasoning and case formulation facilitated by the use of macro-analysis [25]. This latter consists of establishing a relationship between co-occurring syndromes and problems. Macro-analysis is not limited to diagnostic entities, as is the case in the concept of comorbidity in DSM, but also to problems that are judged by the clinician to affect a person's life. Macro-analysis starts from the assumption that, in most cases, there are functional relationships among different problem areas and that the targets of treatment may vary during the course of the disturbances. Different lines of treatment may be chosen at different times. The hierarchical organization that is chosen may depend on a variety of factors (urgency, availability of treatment tools, priorities established by the clinician and/or the patient, etc.) [24,25]. Staging is another key determinant of its use, both in terms of longitudinal development of a disorder and treatment response [26]. Not surprisingly, the three main current indications of WBT are transdiagnostic.
Increasing the Level of Recovery
The sequential combination of CBT and WBT in recurrent depression has resulted in a decreased rate of relapse [10,11,12]. However, this is a general characteristic of trials using the sequential model that consists of pharmacotherapy for addressing the acute symptoms of depression and psychotherapy in its residual phase [27,28]. From the available studies [10,11,12] we have no way of knowing whether WBT was a specific effective ingredient and what the mechanism was in decreasing the likelihood of relapse. A dismantling study that was performed in generalized anxiety disorder [29] suggested that an increased level of recovery could indeed be obtained with the addition of WBT to CBT. Twenty patients were randomly assigned to 8 sessions of CBT or the sequential administration of CBT followed by another 4 sessions of WBT. Both treatments were associated with a significant reduction of anxiety. However, significant advantages of the CBT/WBT sequential combination over CBT were observed, both in terms of symptom reduction and psychological well-being improvement as measured by the CID [8] and the PWB [7]. These results suggested the feasibility and clinical advantages of adding WBT to the treatment of generalized anxiety disorder. The decrease in anxiety, as measured by the CID [8], might be due to the fact that self-monitoring of episodes of well-being may lead to a more comprehensive identification of automatic thoughts than that entailed by the customary monitoring of episodes of distress in cognitive therapy and may thus result in more effective cognitive restructuring. An increase in psychological well-being, as measured by the PWB [7], occurred also with CBT only, but not to the degree that took place with WBT, suggesting a specific mechanism for WBT. Both mechanisms indicate a role for WBT in increasing the level of recovery. While the clinical benefits have been substantiated in depression and generalized anxiety disorder, this appears to be a target for a number of other mental disorders. For instance, Penn et al. [30] have postulated a role for WBT in improving functional outcomes as an additional ingredient to CBT in psychotic disorders. Indeed, subjective well-being appears to be impaired in schizophrenia and is associated with reduced anterior cingulated activity during reward processing, which may induce reduced integration of environmental stimuli, motivated behavior and reward outcome [31].
Modulating Mood
WBT was applied to the treatment of cyclothymic disorder, which involves mild or moderate fluctuations of mood, thought and behavior without meeting formal diagnostic criteria for either major depressive disorder or mania [32]. It is a common and disabling condition that does not attract much research attention since no drugs have been patented for its treatment. Sixty-two patients with cyclothymic disorder were randomly assigned to the sequential combination of CBT and WBT or clinical management. An independent blinded evaluator assessed the patients before treatment, after therapy and at 1- and 2-year follow-ups. The CID [8] and the Mania Scale [33] were used to evaluate symptoms. At posttreatment evaluation, significant differences were found in outcome measures, with greater improvements in the CBT/WBT group compared with clinical management. Therapeutic gains were maintained at 1- and 2-year follow-ups [32]. The results thus indicated that WBT may address both polarities of mood swings and is geared to a state of euthymia, as outlined in table 1. In 1991, Garamoni et al. [34] suggested that healthy functioning is characterized by an optimal balance of positive and negative cognitions or affects, and that psychopathology is marked by deviations from the optimal balance. As pointed out by Wood and Tarrier [23], excessively elevated levels of positive emotions can become detrimental and are more connected with mental disorders and impaired functioning. Can the WBT target of euthymia decrease vulnerability to depression in anxiety disturbances? Why do many patients in the longitudinal course of anxiety disorders develop depression and other patients do not [18]?
Educational Purposes
Three randomized controlled trials in educational settings indicated that protocols based on WBT may be suitable for promoting mechanisms of resilience and psychological well-being [35,36,37] In the first pilot study, school interventions (4 class sessions lasting a couple of hours) were performed in a population of 111 middle-school students randomly assigned to either a protocol using theories and techniques derived from CBT or a protocol derived from WBT. Both school-based interventions resulted in a comparable improvement in symptoms and psychological well-being [35]. This pilot investigation suggested that well-being-enhancing strategies could match CBT in the prevention of psychological distress and in promoting optimal human functioning among children. The differential effects of WBT and CBT approaches have been subsequently explored in another controlled school intervention, involving more sessions and an adequate follow-up [36]. In this trial, 162 students attending middle schools were randomly assigned to either a protocol derived from WBT or an anxiety management protocol. The results of this investigation showed that WBT was found to produce significant improvements in the autonomy scale of PWB [7] and in the friendliness scale of the Symptom Questionnaire [38], whereas anxiety management ameliorated anxiety only.
WBT school interventions were extended to high-school students, who are considered to be a more ‘at risk' population for mood and anxiety disorders [39]. School interventions were performed in a sample of 227 students [37]. The classes were randomly assigned to either a protocol derived from WBT or an attention-placebo protocol, which consisted of relaxation techniques, group discussion of common problems reported by students and conflict resolution. The WBT intervention was found to be significantly more effective in promoting psychological well-being, with particular reference to personal growth, compared with the attention-placebo protocol. Further, it was found to be more effective in decreasing distress, in particular anxiety and somatization. The beneficial effects of the WBT protocol in decreasing anxiety and somatization were maintained at the follow-up, whereas in the attention-placebo group improvements faded and disappeared [37]. The results thus indicated that WBT in educational settings may yield enduring results in terms of positive emotions and psychological well-being. Each session was conducted by two psychologists in the presence of the teacher.
There is little doubt that WBT may display great potential with children and adolescents. The main reason is the high flexibility that characterizes this age population, which lends itself to the achievement of new balances in the terms of Jahoda [17]. This potential may be extended from clinical to educational settings [39].
Emerging Perspectives
A potential role for WBT can be postulated and deserves to be tested in a number of clinical conditions.
Treatment Resistance
WBT may be of particular value in the high proportion of patients who fail to respond to standard pharmacological and/or psychotherapeutic treatments. Six patients with agoraphobia and panic attacks who completed a controlled trial with a cross-over design, encompassing three treatment modalities, namely exposure alone, cognitive therapy with exposure and exposure associated with imipramine [40], but still suffered from panic attacks, were offered a course of WBT. Three patients accepted. WBT was associated with the prolongation of exposure in vivo homework [4]. Of the 3 patients, 2 achieved panic-free status. It is obviously very difficult to draw conclusions from this very small trial, which involved only half of the patients who still suffered from panic disorder. A placebo (nonspecific) effect is possible, even though unlikely in patients who had unsuccessfully undergone three consecutive trials. Since the controlled trial had disclosed a significant effect of the time factor [40], the results might have been simply due to prolongation of exposure. However, it is also possible that WBT helped the 2 patients undergoing exposure and increased their compliance as to exposure homework. This, indeed, appeared to have been improved according to the therapist's ratings [40]. Cosci [41] described the case of a patient with panic disorder, agoraphobia and a major depressive episode who failed to respond to paroxetine and CBT and successfully responded to WBT. This patient was unable to identify automatic thoughts by monitoring distress with cognitive therapy, whereas she was able to do so while monitoring well-being with WBT. Interestingly, after WBT she was able to complete cognitive therapy [41].
WBT has been applied to the case of a depressed patient who displayed treatment resistance. She had responded to an antidepressant drug well; the medication was then tapered and discontinued [42]. Three months later depression came back; this time, however, the same medication that was given the first time did not work. After some pharmacological attempts, the sequential combination of CBT and WBT was attempted. She got better and stayed well. ‘I now have a 12-year follow-up with no relapses and psychotropic medications'. Interestingly, since the mechanisms of oppositional tolerance with antidepressant drugs may involve the HPA axis [42], we also measured 24-hour urinary free cortisol which provides an overall assessment of the production of cortisol. The HPA axis was normalized by CBT/WBT [42]. Future research may disclose whether WBT has a place in treatment resistance in depression. Indeed, 2 other interesting cases were reported in the Netherlands [43]. One involved a patient with depression that was refractory to both pharmacological treatment and CBT and was successfully treated with WBT. In the other case, WBT was applied to a patient with DSM dysthymia and yielded remission [43].
Overcoming Trauma and Increasing Resilience
Two cases have been reported on the use of WBT alone or in sequential combination with exposure for overcoming posttraumatic stress disorder, with the central trauma being discussed only in the initial history-taking session [44]. Research on the neurobiological correlates of resilience has disclosed how different neural circuits (reward, fear conditioning and extinction, social behavior) may involve the same brain structures, particularly the amygdala, the nucleus accumbens and the medial prefrontal cortex [45]. Reconsolidation is a process in which old, reactivated memories undergo consolidation: each time a traumatic memory is retrieved, it is integrated into an ongoing perceptual and emotional experience, which involves NMDA (N-methyl-D-aspartate) and β-adrenergic receptors and requires cAMP (cyclic adenosine monophosphate) response element binding protein induction [45]. Singer et al. [46], on the basis of preclinical evidence, suggested that WBT may stimulate dendrite networks in the hippocampus and induce spine retraction in the basolateral amygdala (a site of storage for memories of fearful or stressful experiences), leading to a weakening of distress and traumatic memories.
There has been growing awareness of the fact that traumatic experiences can also give rise to positive transformations, subsumed under the rubric of posttraumatic growth [47]. Positive changes can be observed in self-concept (e.g. new evaluation of one's strength and resilience), appreciation of new possibilities in life, social relations, hierarchy of values and priorities, and spiritual growth. WBT may be uniquely suited for facilitating the process of posttraumatic growth.
Mental Pain
An issue that is not sufficiently appreciated is the experience of mental pain many patients have [48,49,50,51]. Patients sometimes mention this experience spontaneously, but in other cases only upon specific questions (which, however, are seldom asked). Mental pain may be worse than most forms of physical pain, because it is not localized and often has no apparent reason. Table 2 indicates some characteristics of mental pain, as depicted in a self-rating scale. Grief provides an example of the sense of emptiness, loss of meaning and suffering that mental pain entails. Mental pain may or may not be associated with anxiety and/or depression [48,49,50,51]. It is conceivable and yet to be tested that WBT may counteract the manifestations of mental pain [16]. Since positive affects have been found to attenuate both the perception of physical pain and its affective responses [52], WBT may also entail favorable effects in the case of physical pain.
Discontinuing Psychotropic Drugs
Psychotropic drug treatment, particularly when it is protracted in time, may cause various forms of dependence. Withdrawal symptoms do not necessarily wane after drug discontinuation and may build into a persistent postwithdrawal disorder [53]. These symptoms may constitute an iatrogenic comorbidity that affects the course of illness and the response to subsequent treatments [13]. The discontinuation of antidepressant drugs such as selective serotonin reuptake inhibitors, duloxetine and venlafaxine constitutes a major clinical challenge [53]. A protocol based on the sequential combination of CBT and WBT has been devised and tested in case reports [54]. The addition of WBT, which has also been suggested in substance dependence [55], had the specific function of counteracting the effects of pharmaceutical propaganda on patients. Such effects were remarkably anticipated by Lipowski [56] more than 25 years ago.
‘Another current fad is to tell patients that they suffer from a chemical imbalance in the brain. The explanatory power of this statement is of about the same order as if you said to the patient: ‘‘you are alive''. It confuses the distinction between etiology and correlation, and cause and mechanism, a common confusion in our field. It gives the patient a misleading impression that his or her imbalance is the cause of his or her illness, that it needs to be fixed by purely chemical means, that psychotherapy is useless, and that personal efforts and responsibility have no part to play in getting better' [[56], p. 252].
It is important to convey the message that ‘there is life after antidepressant drugs' and WBT may be a helpful tool in this freedom path. When the catastrophic iatrogenic effects of the inappropriate use of antidepressant drugs, particularly in anxiety disorders, is able to emerge from a very tight censorship [57], the importance of discontinuation strategies will then be fully appreciated [53,57].
Improving Medical Outcomes
The need to include the consideration of psychosocial factors (functioning in daily life, psychiatric and psychological symptoms, quality of life, illness behavior) has emerged as a crucial part of investigation and patient care [58]. These aspects have become particularly important in chronic diseases, where cure cannot take place, and also extend to family caregivers of chronically ill patients and health providers [58]. It is thus conceivable to postulate a role for WBT in the setting of medical disease, to counteract the limitations and challenges induced by illness experience. A randomized controlled trial, headed by Chiara Rafanelli [in preparation], on addressing depressive symptoms and demoralization after myocardial infarction is currently in progress. Patients are being randomized to CBT/WBT sequential combination or clinical management. In some way, what Chiara Rafanelli is attempting to do with patients who suffered from a myocardial infarction pertains to rehabilitation medicine, which is another important potential area of application of WBT. The process of rehabilitation, in fact, requires the persuit of well-being and changes in lifestyle as primary targets of intervention [58].
The use of WBT in the setting of medical disease may not simply be that of promoting psychological well-being and coping in the face of serious illness [59]. In recent years there has been increasing evidence suggesting that stressful conditions may elicit a pattern of CTRA (conserved transcriptional response to adversity), in which there is an increased expression of proinflammatory genes and a concurrent decreased expression of type 1 interferon innate antiviral response and IgG antibody synthesis [60]. Such patterns have been implicated in the pathophysiology of cancer [61] and cardiovascular diseases [62]. Frederickson et al. [63] showed that individuals with high psychological well-being presented reduced CTRA gene expression, which introduces a potential protective role of WBT in a number of medical disorders.
Improving Health Attitudes and Behavior
An unhealthy lifestyle is a major risk factor for many of the most prevalent diseases, such as diabetes, obesity and cardiovascular illness [58]. Switching the general population to healthy lifestyles is a major source of prevention, particularly in the younger population. In adolescents, decreased well-being has been associated with unhealthy behavior, such as smoking, physical inactivity and insufficient sleep [64]. WBT may thus contribute to improve health attitudes and behavior. The American Academy of Pediatrics has underscored the need to address the current epidemic of childhood obesity through enhanced adherence to dietary guidelines and increasing physical activity [65]. Significant impairments in psychological well-being in patients with eating disorders compared with healthy controls have been recently documented [66]. These findings may pave the way for assessing the value of WBT in eating disorders. WBT may particularly address body image disturbances, whether associated with eating disorders or not [67,68].
Conclusions
The studies that are summarized indicate that the potential role of WBT is broader than that originally assumed, that is, decreasing the risk of relapse in the residual phase of mood and anxiety disorders [69]. Its updated scope encompasses increasing resilience in a variety of psychiatric and medical conditions, modulating psychological well-being and mood, and developing alternative pathways to established treatment modalities, including psychotropic drugs. An important characteristic of WBT is self-observation of psychological well-being associated with specific homework. Such a perspective is different from interventions that are labeled as positive but are actually distress oriented. Another important feature of WBT is the assumption that imbalances in well-being and distress may vary from one illness to another and from patient to patient [70]. The pursuit of euthymia [18] can thus only be achieved with a personalized approach that characterizes the treatment protocol and requires a comprehensive initial evaluation. The manualization of WBT [16] may facilitate its individualized application, and the insights gained by clinicians and investigators may refine its current use and indications. The model is realistic, instead of idealistic, and may be frustrating to psychotherapists who are in need of fixed conceptual schemas, but it is in keeping with the complexity of clinical situations that are encountered in everyday practice.
