CBT for difficult-to-treat depression: self-regulation model.

BACKGROUND: Cognitive behavioural therapy (CBT) is an effective treatment for depression but a significant minority of clients do not complete therapy, do not respond to it, or subsequently relapse. Non-responders, and those at risk of relapse, are more likely to have adverse childhood experiences, early-onset depression, co-morbidities, interpersonal problems and heightened risk. This is a heterogeneous group of clients who are currently difficult to treat. AIM: The aim was to develop a CBT model of depression that will be effective for difficult-to-treat clients who have not responded to standard CBT. METHOD: The method was to unify theory, evidence and clinical strategies within the field of CBT to develop an integrated CBT model. Single case methods were used to develop the treatment components. RESULTS: A self-regulation model of depression has been developed. It proposes that depression is maintained by repeated interactions of self-identity disruption, impaired motivation, disengagement, rumination, intrusive memories and passive life goals. Depression is more difficult to treat when these processes become interlocked. Treatment based on the model builds self-regulation skills and restructures self-identity, rather than target negative beliefs. A bespoke therapy plan is formed out of ten treatment components, based on an individual case formulation. CONCLUSIONS: A self-regulation model of depression is proposed that integrates theory, evidence and practice within the field of CBT. It has been developed with difficult-to-treat cases as its primary purpose. A case example is described in a concurrent article (Barton et al., 2022) and further empirical tests are on-going.

Cognitive change in obese adolescents losing weight.

OBJECTIVES: To investigate how obese adolescents think about themselves in terms of exercise, eating, and appearance and whether these cognitions change over the course of a residential weight loss camp. RESEARCH METHODS AND PROCEDURES: Obese adolescents [N = 61; age, 14.1 (+/-0.2) years; BMI, 33.9 (+/-0.7) kg/m(2)] completed assessments of body weight and height and self-esteem and a sentence-completion test eliciting thoughts and beliefs about exercise, eating, and appearance at the start and end of the camp (mean stay, 26 days). They were compared with a single assessment of 20 normal-weight adolescents [age, 15.4 (+/-0.2) years; BMI, 21.8 (+/-0.5) kg/m(2)]. RESULTS: The obese adolescents lost 5.7 kg and reduced their BMI SD score by 0.25. Camp residence was associated with a significant reduction in the number of negative automatic thoughts and an increase in positive thoughts, especially related to exercise and appearance. There was no change in conditional beliefs, either functional or dysfunctional. Including BMI SD score change as a covariate took away all the main and interaction effects of time, showing that cognitive change was largely accounted for by the reduction in weight. Despite this improvement, campers remained cognitively more negative and dysfunctional than the normal-weight comparison adolescents. DISCUSSION: Obese adolescents not only lost weight, but they improved their self-representation, specifically in terms of automatic thoughts about exercise and appearance. Although these are short-term cognitive changes, they reflect positively on the camp experience and show the value of psychological improvement in assessing obesity-treatment outcomes.

Role loss and emotional adjustment in chronic pain.

Chronic pain interrupts behaviour, interferes with functioning, and may affect a person's identity: their sense of self. We tested whether loss of role and personal attributes and current and past self-concept differentiation, predicted adjustment as indexed by measures of depression. Chronic pain patients (n=80) completed measures of pain (MPQ), disability (PDI), depression and anxiety (BDI, HADS). Measures of role and attribute loss and self-concept differentiation were derived from a Role-Attribute Test in which participants identified four social roles in four domains (friendship, occupation, leisure, family) and nominated two personal attributes in each role prior to pain onset and current. Participants reported mean losses of 3.38 roles, and 6.97 attributes. Greater losses were observed in friendship, occupation and leisure domains compared with the family domain. Multiple regression analyses revealed that after controlling for demographic and clinical differences, role and attribute loss predicted depression scores. There was no evidence that depression was associated with past self-concept differentiation. The results are discussed with reference to the methodology used and the relevance of self-identity to understand adjustment to chronic pain.
