Applied Psychology: Health and Well-Being. (Epub ahead of print). doi: 10.1111/aphw.12190. (Early view – Jan 23rd, 2020)
Background: Using the motivational phase of the Health Action Process Approach (HAPA), this study examined whether sedentary behaviour and diabetes information is a meaningful source of motivation to reduce daily sitting time among preintending office workers. Methods: Participants (N = 218) were randomised into HAPAâintervention (sedentary behaviour), HAPAâattention control (physical activity), or control (no treatment) conditions. Following treatment, purposeâbuilt sedentaryârelated HAPA motivational constructs (risk perception, outcome expectancies, selfâefficacy) and goal intentions were assessed. Only participants who had given little thought to how much time they spent sitting (preintenders) were used in subsequent analyses (n = 96). Results: Significant main effects favouring the intervention group were reported for goal intentions: to increase number and length of daily breaks from sitting at work; to reduce daily sitting time outside of work; to increase daily time spent standing outside of work, as well as for outcome expectancies (p values â¤ .05; É³p2 values â¥.08). Only selfâefficacy (Î² range = 0.39â0.50) made significant and unique contributions to work and leisureâtimeârelated goal intentions, explaining 11â21 per cent of the response variance. Conclusions: A brief, HAPAâbased online intervention providing information regarding sedentary behaviour and diabetes risk may be an effective source of motivation.

This chapter covers the theoretical basis of psychological interventions to prevent athletic injury, highlights the importance of psychosocial factors, provides a literature review of psychological based interventions to prevent injury, outlines methodological issues for future injury prevention research, and discusses practical implications for athletes, coaches, trainers, and other sports personnel.

Applied Psychology: Health and Well-Being. (Epub ahead of print). doi: 10.1111/aphw.12201. (Early view – Apr 27th, 2020)
Background: Officeâworking adults represent an atârisk population for high levels of sedentary behaviour (SB), which has been associated with an increased risk for numerous chronic diseases. This study examined the effectiveness of a Health Action Process Approach (HAPA) based planning intervention augmented with tailored text messages to reduce workplace sitting time (primary outcome) and increase specific nonâSBs (i.e. standing time, walking time, stretching time, break frequency, break duration). A secondary purpose was to examine relationships among HAPA volitional constructs and sedentary and nonâSBs. Methods: Fullâtime office workers (Mage = 45.18 Â± 11.33 years) from Canada were randomised into either a HAPA intervention (n = 29) or control (n = 31) condition. Workplace sitting time, time spent in specific nonâSBs, and HAPA volitional constructs were assessed at baseline, weeks 2, 4, 6 (postâintervention), and 8 (followâup). Results: Significant group by time interaction effects, that favoured the intervention group, were found for sitting time (p = .003, É³p2 = .07), standing time (p = .019, É³p2 = .05), and stretching time (p = .001, É³p2 = .08) as well as for action planning (p < .001, É³p2 = .20), coping planning (p < .001, É³p2 = .18), and action control (p < .001, É³p2 = .15). Significant correlations (p < .05) were also found between the HAPA constructs and time spent sitting, standing, walking, as well as break frequency. Conclusions: Augmenting a HAPAâbased planning intervention with text messages can reduce workplace sitting time in office workers.
