Health Psychology Review

The General Health Questionnaire (GHQ-12) is a popular measure of psychological distress. Despite its widespread use, an ongoing controversy pertains to its internal structure. Although the GHQ-12 was originally constructed to capture a unitary construct, empirical studies identified different factor structures. Therefore, this study examined the dimensionality of the GHQ-12 in two independent meta-analyses. The first meta-analysis used summary data published in 38 primary studies (total N = 76,473). Meta-analytic exploratory factor analyses identified two factors formed by negatively and positively worded items...

Low self-control is associated with increased consumption of alcohol, tobacco, and unhealthy food. This systematic review aimed to assess whether individual differences in self-control modify the effectiveness of interventions to reduce consumption of these products, and hence their potential to reduce consumption amongst those whose consumption is generally greater. Searches of six databases were supplemented with snowball searches and forward citation tracking. Narrative synthesis summarised findings by: consumption behaviour (alcohol, tobacco, food); psychological processes targeted by the intervention (reflective, non-reflective, or both); and study design (experiment, cohort, or cross-sectional)...

Use of fear appeals assumes that when people are emotionally confronted with the negative effects of their behavior they will change that behavior. That reasoning is simple and intuitive, but only true under specific, rare circumstances. Risk-perception theories predict that if people will experience a threat, they want to counter that threat. However, how they do so is determined by their coping efficacy level: if efficacy is high, they may change their behavior in the suggested direction; if efficacy is low, they react defensively...

Researchers have speculated that sedentary behaviour may reduce health-related quality of life (HRQOL), but the extent to which this is true remains unknown. Our study sought to systematically review and synthesise research on the relationship between sedentary behaviours and HRQOL and to investigate if these relationships are moderated by age, health status, and HRQOL domain. The review was registered with PROSPERO (no. CRD42016036342). We searched six electronic databases. The selection process resulted in including k = 27 original studies; k = 18 were included in a meta-analysis...

Active school travel (AST) is an important source of physical activity for children and a conceptual understanding of AST is necessary to inform promotion efforts. The aim of this paper is to provide a conceptual analysis of AST. All currently identified AST formulations include intra-individual variables which are often recommended as intervention targets. However, existing literature lacks clarity on precisely how these intra-individual variables might shape specific AST interventions. Moreover, evaluative studies of AST interventions typically fail to specify an underpinning theory or model...

The methods employed to measure behaviour in research testing the theories of reasoned action/planned behaviour (TRA/TPB) within the context of health behaviours have the potential to significantly bias findings. One bias yet to be examined in that literature is that due to common method variance (CMV). CMV introduces a variance in scores attributable to the method used to measure a construct, rather than the construct it represents. The primary aim of this study was to evaluate the impact of method bias on the associations of health behaviours with TRA/TPB variables...

This systematic review and meta-analysis aimed to clarify the associations between meaning in life and physical health using random-effects models. Conceptualisation of meaning (order in world vs. purpose in life), type of health indicators, participants' health status, and age issues were investigated as moderators. Systematic searches of six databases resulted in inclusion of k = 66 studies (total N = 73,546). Findings indicated that meaning in life and physical health formed weak-to-moderate associations (the overall estimate of the average effect = 0...

While considerable evidence suggests that interval exercise confers numerous physiological adaptations linked to improved health, its psychological consequences and behavioural implications are less clear and the subject of intense debate. The purpose of this scoping review was to catalogue studies investigating the psychological responses to interval exercise in order to identify what psychological outcomes have been assessed, the research methods used, and the results. A secondary objective was to identify research issues and gaps...

Following surgery, some patients suffer distress, disappointment, regret, poor adjustment, and poor quality-of-life. Surgeons may define 'success' based on objective clinical outcomes, but patients' perceptions of surgical success rely primarily on a comparison to their initial expectations. We review the literature on the relationship between patients' surgical expectations and psychosocial outcomes and attempt to resolve a conflict in the literature. Specifically, we propose that conflicting conclusions regarding the merits of optimism primarily stem from differing methodological approaches by researchers in the field...

n-of-1 studies test hypotheses within individuals based on repeated measurement of variables within the individual over time. Intra-individual effects may differ from those found in between-participant studies. Using examples from a systematic review of n-of-1 studies in health behaviour research, this article provides a state of the art overview of the use of n-of-1 methods, organised according to key methodological considerations related to n-of-1 design and analysis, and describes future challenges and opportunities...

Various lines of research have identified a number of factors that can impair a person's ability and motivation to exercise self-control, here self-regulation, in the face of a tempting object (e.g., food, sex, alcohol/drugs, smoking). Each of these in situ factors - the availability of the tempting object, one's desire for it, and impaired affective and cognitive functioning (most notably from sleep-related fatigue, daily 'wear and tear', and intoxication) - makes self-regulation more difficult, and even more so when they co-occur...

The aim of the current article is to provide a brief introduction to Bayesian statistics within the field of health psychology. Bayesian methods are increasing in prevalence in applied fields, and they have been shown in simulation research to improve the estimation accuracy of structural equation models, latent growth curve (and mixture) models, and hierarchical linear models. Likewise, Bayesian methods can be used with small sample sizes since they do not rely on large sample theory. In this article, we discuss several important components of Bayesian statistics as they relate to health-based inquiries...

N-of-1 studies are based on repeated observations within an individual or unit over time and are acknowledged as an important research method for generating scientific evidence about the health or behaviour of an individual. Statistical analyses of n-of-1 data require accurate modelling of the outcome while accounting for its distribution, time-related trend and error structures (e.g., autocorrelation) as well as reporting readily usable contextualised effect sizes for decision-making. A number of statistical approaches have been documented but no consensus exists on which method is most appropriate for which type of n-of-1 design...

Individual studies of health psychology are samples taken in particular places at particular times. The results of such studies manifest multiple processes, including those associated with individual, sample, intervention, and study design characteristics. Although extant meta-analyses of health phenomena have routinely considered these factors to explain heterogeneity, they have tended to neglect the environments where studies are conducted, which is ironic, as health phenomena cluster in space and times (e...

Statistical methods play an important role in behavioural, medical, and social sciences. Two recent statistical advances are structural equation modelling (SEM) and meta-analysis. SEM is used to test hypothesised models based on substantive theories, which can be path, confirmatory factor analytic, or full structural equation models. Meta-analysis is used to synthesise research findings in a particular topic. This article demonstrates another recent statistical advance - meta-analytic structural equation modelling (MASEM) - that combines meta-analysis and SEM to synthesise research findings for the purpose of testing hypothesised models...
