AI Article Synopsis
- The study investigates the effectiveness of the Health Action Process Approach (HAPA) in promoting health behavior change among older adults, focusing on both individual and group levels.
- The research included two longitudinal studies on physical activity and medication adherence, assessing various HAPA components over time.
- While HAPA was mostly effective at the group level, individual-level findings showed only action control as a reliable predictor for behavior change.
Article Abstract
Background: Health behavior change theories usually claim to be universally and individually applicable. Most research has tested behavior change theories at the interindividual level and within young-to-middle-aged populations. However, associations at the interindividual level can differ substantially from associations at the intraindividual level. This study examines the applicability of the Health Action Process Approach (HAPA) at the inter- and the intraindividual level among older adults.
Methods: Two intensive longitudinal studies examined the HAPA model covering two different health behaviors and two different time spans: Study 1 (physical activity, N = 52 × 6 monthly observations) and Study 2 (medication adherence, N = 64 × 30 daily observations). The HAPA constructs (risk awareness, outcome expectancy, self-efficacy, intention, action planning, action control), and self-reported behaviors were assessed.
Results: Overall, at the interindividual level, results of both studies largely confirmed the associations specified by the HAPA. At the intraindividual level, results were less in line with the HAPA. Only action control emerged as consistent predictor of behavior.
Conclusions: This study emphasises the importance of examining health behavior change theories at both, the inter- and the intraindividual level.

Background And Objectives: To determine whether intra-individual differences in pre-donation blood test results were associated with vasovagal reactions (VVRs).
Materials And Methods: The study included donors who voluntarily donated 400 mL of whole blood at least twice during a 5-year blood collection period of the Japanese Red Cross, including both donations with and without a VVR. A conditional logistic regression analysis by age group and sex was conducted, using each donor as a stratum, together with an analysis of deviance to test the significance of including an interaction term between age group and blood data in the regression model.
Investigating context-specific sedentary behaviours and cardiometabolic health in college-based young adults (CONTEXT-SB): a protocol for a longitudinal observational study.

Background: Sedentary behaviour (SB) is detrimental to cardiometabolic disease (CMD) risk, which can begin in young adulthood. To devise effective SB-CMD interventions in young adults, it is important to understand which context-specific SB (CS-SB) are most detrimental for CMD risk, the lifestyle behaviours that cluster with CS-SBs and the socioecological predictors of CS-SB.
Methods And Analysis: This longitudinal observational study will recruit 500 college-aged (18-24 years) individuals.
Examining Longitudinal Relations Between Eating Disorder Symptoms and Negative Emotion Variability in Military Members.

Up to a third of service members and Veterans experience disordered eating. Disordered eating can be maintained through negative reinforcement of painful and unpleasant emotions such as guilt, shame, sadness, and hostility. Hostility is a negative emotion that may be particularly relevant for service members and Veterans, yet hostility's relation to disordered eating remains understudied.

This study examined the association between cognitive intra-individual variability (IIV), a non-mean-based indicator of underlying neuropathology, and self-reported everyday functioning of 1,086 women with HIV (WWH) and 494 socio-demographically similar women without HIV (WWoH). Objective cognitive performance across seven domains and the self-rated Lawton & Brody scale of Instrumental Activities of Daily Living (IADL) were assessed among participants of the Women's Interagency HIV Study. Two types of cognitive IIV were calculated by taking the standard deviation across seven cognitive domains to calculate dispersion: 1) intra-individual standard deviation (denoted as IIV) and 2) coefficient of variation (denoted as IIV).

In the Philippines, the co-occurrence of two or more types of malnutrition in an individual, also known as intra-individual double burden of malnutrition (DBM), has rarely been investigated. This study aimed to determine the prevalence of and the factors associated with DBM at the individual level among Filipino women of reproductive age (WRA) using the data collected from the 2018 Philippine Expanded National Nutrition Survey. For this study, intra-individual DBM was defined as the co-existence of overweight or obesity and anemia in an individual.
