Effects of exercise self-regulation on subsequent eating self-regulation: Implications for depletion vs. improvement based on behavioral treatment foci

IntroductionAn improved understanding of individuals’ ability to self-regulate through barriers in the management of their weight-loss behaviors is important. Although self-regulation related to exercise might carry-over to increased eating-related self-regulation through the development of such skills, it also might be depleted because self-regulation is thought to be a limited resource. Additionally, mood might affect self-regulation change.ObjectiveThis field study aimed to determine if exercise-related self-regulation was associated with subsequent eating-related self-regulation, how treatment foci affected that relationship, and if mood change concurrently influenced self-regulation.MethodAn educational weight-loss treatment (n = 52) and a behaviorally based self-regulatory-focused treatment (n = 57) was administered to women with obesity via a community health-promotion setting. Baseline – Month 3 changes in their exercise self-regulation and overall negative mood, and Months 3–6 change in eating self-regulation, were assessed.ResultsImprovements were significantly greater in the self-regulation treatment group on exercise self-regulation, eating self-regulation, and mood. For the self-regulation group, there was a significant positive relationship between changes in exercise self-regulation and eating self-regulation, β = 0.27, p = 0.044. Conversely, the association of those variables was significant and inverse in the educational group, β = −0.29, p = 0.039. Reduction in negative mood was significantly related to increased exercise self-regulation, across groups, β = −0.32, p = 0.001.ConclusionWhen self-regulation was focused upon and rehearsed within an exercise context, its changes positively affected subsequent changes in eating self-regulation. However, when self-regulation was not targeted, self-regulation used for maintaining exercise depleted eating-focused self-regulation. Findings contributed to self-regulatory theory and had implications for the improvement of behavioral weight-loss treatments.     

Sudden gains in cognitive behavioral treatment for depression: when do they occur and do they matter?

Despite the use of efficacious treatments for depression, individuals differ in both the degree to which they recover and the rate at which recovery occurs. Tang and colleagues found that depressed patients who had sudden improvements in their symptomatology not only maintained these gains, but also enjoyed more improvement and higher rates of recovery than those without sudden gains (J. Consulting Clin. Psychol. 67(6) (1999) 894; J. Consulting Clin. Psychol. 70(2) (2002) 444). Our study examined the role of sudden gains in a cognitive-behavioral group treatment for depression. Results indicated that 41.9% of patients experienced sudden gains. Furthermore, sudden gains occurring in the first third of treatment appear to have special importance. Participants enjoying early sudden gains had significantly larger changes in depressive symptom scores over the course of treatment than those without sudden gains and were marginally more likely to be treatment responders compared to those without early sudden gains. In contrast to Tang and DeRubeis (J. Consulting Clin. Psychol. 67(6) (1999) 894), however, sudden gains were not associated with cognitive changes.     

A preliminary investigation of acceptance and commitment therapy as a treatment for chronic skin picking

The effectiveness of a deliberately limited version of Acceptance and Commitment Therapy (ACT) for chronic skin picking was evaluated in a pair of multiple baseline across participants designs. Self-monitoring of skin picking showed that four of the five participants reached near zero levels of picking by post-treatment, but these gains were not fully maintained for three of the four participants at follow-up. The findings of the self-reported skin picking were generally corroborated by ratings of photographs of the damaged areas and by ratings on a validated measure of skin picking severity. All participants rated the intervention as socially acceptable, and reductions were found on measures of anxiety, depression, and experiential avoidance for most participants as a result of the intervention. Results support the construction of more comprehensive ACT protocols for skin picking.     

Evaluation of therapist-supported parent-implemented CBT for anxiety disorders in rural children

Supplementing bibliotherapy with therapist-client communication has been shown to be an effective way of providing services to under-resourced and isolated communities. The current study examined the efficacy of supplementing bibliotherapy for child anxiety disorders with therapist-initiated telephone or email sessions, or with client-initiated contact in a randomised trial using a waitlist control. Participants were 100 anxiety-disordered children and their parents from rural and remote communities. All treatment conditions resulted in improvement on self-report measures and clinician rated severity. Telephone sessions produced superior outcomes with 79% of children being anxiety disorder free post-treatment compared with 33% of email and 31% of client-initiated participants. The results suggest that therapist supplemented bibliotherapy could provide an efficacious treatment option for families isolated from traditional treatment services.     

Habit reversal versus supportive psychotherapy in Tourette's disorder: a randomized controlled trial and predictors of treatment response

Tourette syndrome (TS) is characterized by chronic motor and vocal tics. Habit reversal therapy (HR) is a behavioral treatment for tics which has received recent empirical support. The present study compared the efficacy of HRT in reducing tics, improving life-satisfaction and psychosocial functioning in comparison with supportive psychotherapy (SP) in outpatients with TS. In addition, we investigated whether impairments in response inhibition in patients with TS predict response to HR treatment which specifically aims to inhibit tics. Thirty adult outpatients with DSM-IV TS were randomized to 14 individual sessions of HR (n = 15); or SP (n = 15). HR but not SP reduced tic severity over the course of the treatment. Both groups improved in life-satisfaction and psychosocial functioning during active treatment. Reductions in tic severity (HR) and improvements in life-satisfaction and psychosocial functioning (HR and SP) remained stable at the 6-month follow-up. The extent of pre-treatment response inhibition impairment in the HR group predicted reductions in tic-severity from pre- to post-treatment. Our results suggest that HR has specific tic-reducing effects although SP is effective in improving life-satisfaction and psychosocial functioning. Assessments of response inhibition may be of value for predicting treatment response to HR.     

The management of unwanted pre-sleep thoughts in insomnia: distraction with imagery versus general distraction

Insomniacs commonly complain that they are unable to get to sleep at night due to unwanted thoughts, worries and concerns. The present study investigated whether brief training in identifying and elaborating an interesting and engaging imagery task for use during the pre-sleep period can reduce unwanted pre-sleep cognitive activity and sleep onset latency. Forty one people with insomnia were given one of three instructional sets to follow on the experimental night; instructions to distract using imagery, general instructions to distract, or no instructions. Based on previous findings reported by Salkovskis & Campbell (1994) 'Behaviour Research and Therapy 32 (1994) 1' and ironic control theory (Wegner, 1994) 'Psychological Review 101 (1994) 34', it was predicted that (1) "imagery distraction" would be associated with shorter sleep onset latency and less frequent and distressing pre-sleep cognitive activity compared to the "no instruction" group and that (2) "general distraction" would be associated with longer sleep onset latency and more frequent and distressing pre-sleep cognitive activity compared to the "no instruction" group. Support was found for the first but not the second prediction. The success of the "imagery distraction" task is attributed to it occupying sufficient "cognitive space" to keep the individual from re-engaging with thoughts, worries, and concerns during the pre-sleep period. In addition, "imagery distraction" involved a very specific alternative cognitive task hence the operating process was given a feature positive search, conditions where mental control is likely to be achieved.     

Community based cognitive therapy in the treatment of posttraumatic stress disorder following the Omagh bomb

Studies in academic research centres with selected patients have shown that several cognitive behaviour therapies are effective in the treatment of PTSD following traumas affecting individuals or small groups. Little information is available on the extent to which these positive findings will generalize to more routine clinical settings with less selected patients or to a trauma that affects a whole community. The present study addresses these generalization issues. A consecutive series of 91 patients with PTSD resulting from a car bomb which exploded in the centre of Omagh, Northern Ireland in August 1998 were treated with cognitive therapy, along lines advocated by Ehlers and Clark (2000). There were no major exclusion criteria and 53% of patients had an additional axis I disorder (comorbidity). Therapists were NHS staff with heavy caseloads and modest prior training in CBT for PTSD. A brief training in specialist procedures for PTSD was provided. Patients received an average of eight treatment sessions. Significant and substantial improvements in PTSD were observed. Degree of improvement was comparable to that in previously reported research trials. Comorbidity was not associated with poorer outcome, perhaps because comorbid patients were given more sessions of treatment (average 10 vs 5 sessions). Patients who were physically injured improved less than those who were not physically injured. Overall, the results indicate that the positive findings obtained in research settings generalize well to a frontline, non-selective service.     

Clinical perfectionism: a cognitive-behavioural analysis

This paper reviews the characteristics of clinical perfectionism and proposes a new definition of the phenomenon. It is suggested that the defining feature of clinically significant perfectionism is the overdependence of self-evaluation on the determined pursuit (and achievement) of self-imposed personally demanding standards of performance in at least one salient domain, despite the occurrence of adverse consequences. It is suggested that such clinical perfectionism is maintained by the biased evaluation of the pursuit and achievement of personally demanding standards. Specifically, it is suggested that people with perfectionism react to failure to meet their standards with self-criticism. If they do meet their standards, the standards are re-evaluated as being insufficiently demanding. Anorexia nervosa and bulimia nervosa are considered to have a particular relationship to perfectionism, with both disorders often being direct expressions of perfectionism. Under these circumstances self-evaluation is dependent on the pursuit and attainment of personally demanding standards in the domain of control over eating, shape and weight. The implications of this analysis for research and practice are considered.
