Determinants of weekly sitting time: Construct validation of an initial COM-B model and comparison of its predictive validity with the Theory of Planned Behaviour
OBJECTIVE: In relation to sitting behaviour, to investigate which theoretical domains best formed the Capability, Opportunity, and Motivation constructs of the COM-B, and compare the predictive validity to the Theory of Planned Behaviour (TPB), taking habit strength into consideration. DESIGN: Using a prospective design, 186 adults completed measures capturing domains from the Theoretical Domains Framework for the three COM-B constructs, and habi…
A prospective study exploring the construct and predictive validity of the COM-B model for physical activity
This study examined the constructs of capability, opportunity and motivation from the COM-B model and their influence on moderate-to-vigorous physical activity. Using a prospective survey design, 186 healthy adults completed measures representing the theoretical domains framework mapped to the COM-B, and moderate-to-vigorous physical activity 1 week later. The main indicators for the COM constructs were 'habits' (Capability), 'subjective norms' (…
The effect of current and anticipated body pride and shame on dietary restraint and caloric intake
Social cognitive predictors of intention to test for variant Creutzfeldt-Jakob disease in those affected by haemophilia and other clotting disorders
Individuals with bleeding disorders are at increased risk of variant Creutzfeldt-Jakob disease. This study explored social cognitive predictors of screening intentions. Ninety men and women with bleeding disorders, recruited through the Haemophilia Society, completed an extended Theory of Planned Behaviour questionnaire to predict intention to screen for variant Creutzfeldt-Jakob disease. Extended Theory of Planned Behaviour variables accounted f…
Brief report: Effect of dietary restraint on fruit and vegetable intake following implementation intentions
This study explored whether the effects of implementation intentions on increasing fruit and vegetable intake were moderated by dietary restraint. In total, 208 participants were randomly allocated to control or implementation intention conditions where they were asked to write down when, where and how they would increase their fruit and vegetable intake. Implementation intentions increased fruit and vegetable intake but only in participants scor…
A Randomized Controlled Two-Stage Trial in the Treatment of Bulimia Nervosa, Comparing CBT Versus Motivational Enhancement in Phase 1 Followed by Group Versus Individual CBT in Phase 2
Objective: To conduct a randomized, controlled, two-stage trial in the treatment of bulimia nervosa, comparing cognitive-behavioral therapy (CBT) versus motivational enhancement in Phase 1 followed by group versus individual CBT in Phase 2. Methods: A total of 225 patients with bulimia nervosa or eating disorder not otherwise specified (EDNOS) were recruited into a randomized controlled trial lasting 12 weeks with follow-ups at 1 year and 2.5 yea…
An Exploration of Eating Disorders in a Georgian Sample
Background: There is debate as to whether eating disorders may be culture-bound. However, accumulating evidence suggests that eating disorders may be found outside of the West, although the precise form of the eating disorder may differ. Aims: There were two aims of this study: (1) to translate and establish the psychometric properties of standard questionnaires to measure eating pathology in a Georgian sample; (2) to use these measures to determ…
Online Longitudinal Survey Research: Viability and Participation
This article explores the viability of conducting longitudinal survey research using the Internet in samples exposed to trauma. A questionnaire battery assessing psychological adjustment following adverse life experiences was posted online. Participants who signed up to take part in the longitudinal aspect of the study were contacted 3 and 6 months after initial participation to complete the second and third waves of the research. Issues of data …
Psychosocial factors in the onset of eating disorders: Responses to life‐events and difficulties
A number of studies have proposed a role for stress in the onset of eating disorders. Initially the focus was on the life‐events and difficulties themselves. However, the aim of this study was to examine the coping and support elicited in response to the crises that precipitate onset of eating disorders. Thirty‐two women who had developed an eating disorder within four years of presentation were administered semi‐structured interviews asking abou…
To change or not to change—‘How’ is the question
The objective was to apply the ‘trans‐theoretical’ model of change to a group of patients with eating disorders. Patients were studied in an in‐patient setting. Two sets of questionnaires were used, one to assess ‘stage’ of change, the other to measure the ‘processes’ used to achieve change. Three stages and eight processes were examined. Thirty‐five patients completed the study. Highest scores were found in the contemplation, and lowest in the p…
