Sun protective behaviour,optimism bias,and the transtheoretical model of behaviour change

This study investigated the relationship between sun protective behaviours and three psychological variables influencing health behaviour: decisional balance, optimism bias, and the transtheoretical model of behaviour change. Two hundred participants completed the ‘Readiness to Alter Sun Protective Behaviour’ questionnaire, and a short questionnaire investigating optimism bias, decisional balance, attitudes, and experiences of sun protection and skin cancer. Participants were evenly distributed between the precontemplation, contemplation, and action stages. Participants in the action stage were significantly more likely to endorse the perceived advantages associated with sun protective behaviour than participants in the precontemplation and contemplation stages. They also reported sunbathing significantly less—and being more concerned about contracting skin cancer—than participants in the earlier stages. Decisional balance and optimism bias scores varied systematically across the stages of change; however, decisional balance was the only significant psychological predictor of sun protective behaviours. Optimism bias was greatest in the precontemplation stage, whereas the action stage was characterised by more positive attitudes to sun protection. This suggests that knowledge of the real risks of skin cancer might be a precursor to behaviour change, but only a change in attitudes results in a move to the action stage and measurable behaviour change.     

Why Don't Continents Move? Why Don't People Change?

People don't change because they can't, don't want to, don't know how, or don't know what to change. The transtheoretical model provides an integ-rative model for understanding reasons for not changing, as well as readiness to change. Stages and levels of change guide therapists in their work in helping clients change. Clients in the precontemplative stage typically cannot change without special help. Those in the contemplation stage are not sure they want to change. Those in the preparation stage are afraid they do not know how to successfully change. The levels of change help guide therapists and clients on what to change.     

Tackling conflict: a beyond opposites approach

The issue of conflict is pervasive to most human undertakings at both individual/intra level and group level. Conflicts are the source of internal and external suffering. It has been argued by many authors that although humans have advanced in the technological sphere tremendously and managed to find solutions to countless scientific and material challenges, their ability to effectively resolve internal and external aspects of conflicts remains elusive. Given the level of pain and suffering that can derive from both psychological and social conflicts, it can be argued that any advances in helping improve the resolution of conflicts can have immense benefits in alleviating human suffering making this issue a very worthwhile area of study. Accordingly this paper aims to describe a developing counselling methodology for addressing conflict. The methodology, which was originally inspired by Fuzzy Logic, adopts a cognitive behavioural therapy (CBT) perspective despite awareness of its limitations. The paper traces the origins of the methodology and the areas within counselling it could be applied to. The paper concludes with recommendations regarding the relevance of this approach to an increasingly multicultural environment.     

Evidence That a Very Brief Psychological Intervention Boosts Weight Loss in a Weight Loss Program

Reducing morbidity and mortality associated with being overweight is a crucial public health goal. The aim of the present research was to test the efficacy of a very brief psychological intervention (a volitional help sheet) that could be used as an adjunct to standard weight loss programs to support increased weight loss in an overweight sample. Seventy-two overweight participants currently participating in a weight loss program were randomly allocated to either an intervention (volitional help sheet) condition or a control (distracter task) condition. The main outcome measure was weight at 1-month follow-up. Participants in both conditions lost significant amounts of weight, but those in the intervention condition lost significantly more than those in the control condition (d = 0.66). The findings support the efficacy of the volitional help sheet to promote additional weight loss in an overweight sample engaged in a weight loss program. The volitional help sheet therefore represents a very brief, low-cost intervention that could be used to supplement ongoing weight-loss programs.     

Do hospital treatments represent a ‘teachable moment’ for quitting smoking? A study from a stage-theoretical perspective

Hospital treatments are assumed to be a ‘teachable moment’. This phenomenon, however, is only poorly conceptualised and untested. A stage-theoretical perspective implies that a cueing event such as hospital treatments is a teachable moment if a stage progression, change of cognitions, or both occur. This concept is examined in a cross-sectional study by comparing smokers in two treatment settings, an emergency department (ED) and inpatient treatment after elective surgery, with smokers in a control setting. Setting differences were hypothesised in stage distribution, and levels of and stage differences in social-cognitive factors under control for possible confounders. Stage, social-cognitive factors and possible confounders were assessed in 185 ED smokers, 193 inpatient smokers and 290 control smokers. Compared to control smokers, ED and inpatient smokers were in higher stages; they perceived fewer risks and cons; inpatient smokers reported more concrete plans. Stage differences in self-efficacy among ED and inpatient smokers differed from those among control smokers, but the former corresponded more strongly to the theoretical stage assumptions. The results suggest that hospital treatments lead to a stage progression and change of corresponding cognitions, and thus represent a ‘teachable moment’. Stage-matched interventions should be provided but consider differences in cognitions to be effective.     

Interpreting cross-sectional data on stages of change

Abstract

The vast majority of studies investigating stage theories of health behaviour such as the transtheoretical model have used a cross-sectional research design. Participants are classified into stages and compared on theoretically relevant variables. This paper discusses the proper interpretation of cross-sectional data on stages of change. Linear patterns are not consistent with the stage model assumption that different causal factors are important at different stages but discontinuity patterns (patterns that do not show consistent increments or decrements across stages) can be diagnostic of a stage model. Researchers who use cross-sectional designs should specify predictions concerning the patterns to be expected under a stage model and under possible rival models, and interpret their data accordingly. Wherever possible, they should conduct prospective longitudinal and experimental studies which enable stronger inferences to be drawn.     

大学生网络使用利弊权衡问卷的编制

在前期访谈并结合国内外已有研究的基础上,编制网络成瘾领域的利弊权衡问卷(Internet Addiction Decisional Balance Questionnaire,简称IDBQ)。被试为选自北京市7所高校的1166名大学生,按大约2∶3的方式将被试随机分成两组(N₁=441,N₂=725)分别用于探索性因素分析和验证性因素分析。结果表明IDBQ由好处分问卷和代价分问卷组成,其中好处分问卷维度包括放松心情、获取知识、方便交流和获得成就感;代价分问卷维度包括空虚苦恼、荒废学业、人际受损、浪费金钱。IDBQ具有良好的信度和效度指标,可以作为我国大学生网络使用利弊权衡的测量工具。     

The relationship among the transtheoretical model of behavioral change,psychological distress,and diet attitudes in obesity: Implications for primary care intervention

Obesity is prevalent but undertreated in primary care. Family practice volunteer outpatients (N=454) were administered the Stage of Change for Weight (URICA), the Brief Symptom Inventory (BSI), and the Diet Readiness Test (DRT) to assess the relationship between these variables and obesity. The body mass index (BMI) was used to classify obesity revealing 197 patients with elevated BMI's. There was no significant difference between the obese and the nonobese on any of the psychological measures. The obese reported significantly more difficulty setting diet goals and less control over their eating, ate more to emotional situations, and exercised less than the nonobese. The obese sample (46.7%) reported being in the Action stage of change for weight management. Implications for intervention in primary care include targeting attitudes (DRT) and dispelling physician attitudes that obese individuals have increased levels of psychological distress. Addressing Stage of Change for weight management can facilitate tailoring the appropriate intervention when used in concert with the DRT variables.
