“…In a secondary analysis of two studies, Shapiro-Luft and Cappella (2013) confirm that motivational confounding can be detected in web-based studies with video content. It has been of consideration in conducting real-time multiplayer experiments on the web (Hawkins, 2015) and is now routinely used as an argument to conduct studies on the web rather than in the lab (e.g., Lithopoulos et al, 2020; Sheinbaum et al, 2013).…”

Abstract. The present article reviews web-based research in psychology. It captures principles, learnings, and trends in several types of web-based research that show similar developments related to web technology and its major shifts (e.g., appearance of search engines, browser wars, deep web, commercialization, web services, HTML5…) as well as distinct challenges. The types of web-based research discussed are web surveys and questionnaire research, web-based tests, web experiments, Mobile Experience Sampling, and non-reactive web research, including big data. A number of web-based methods are presented and discussed that turned out to become important in research methodology. These are one-item-one-screen design, seriousness check, instruction manipulation and other attention checks, multiple site entry technique, subsampling technique, warm-up technique, and web-based measurement. Pitfalls and best practices are described then, especially regarding dropout and other non-response, recruitment of participants, and interaction between technology and psychological factors. The review concludes with a discussion of important concepts that have developed over 25 years and an outlook on future developments in web-based research.

“…Physical inactivity is rapidly increasing in low- to middle-income countries [ 4 ]. There is a considerable variety of physical inactivity in different geographical regions of the world because this risk factor is highly influenced by age, gender, health status, self-efficacy (SE), and motivation [ 3 , 5 ]. Based on the data disseminated by the World Health Organization, the inadequate PA caused 9% of the global deaths [ 6 ].…”

Promoting sustainable physical activity among middle-aged Iranian women: a conceptual model-based interventional study

Background Physical inactivity enhances the risk of adverse health conditions such as non-communicable diseases, morbidity, and mortality among middle- and older-aged population. This study is aimed to design, implement, and evaluate a conceptual model of physical activity (PA) promotion among middle-aged Iranian women (MAIW). Methods An interventional study was conducted with 80 women aged between 30 and 59 years in intervention and control groups during 2018–2019. The subjects referred to health centers were selected by the available convenience sampling method. Data collection tools to assess the MAIW' PA level (metabolic equivalent tasks (MET)-min/week) included face-to-face interviews, body mass index (BMI) measurements, the four-question form of PA vital signs in the framework of Iran's Package of Essential Non-communicable (IraPEN) program, and the questionnaire is based on the Health Belief Model (HBM) constructs. Results The intervention led to a three-fold increase in the average PA (from 280.63 to 927.70 MET-min/week) of the intervention group. Although no significant difference in the BMI between both groups was found before the intervention, this educational program decreased the mean BMI from 30.36 to 28.83 kg/m2 (p = 0.01). After the intervention, the values of HBM-based perceived sensitivity/severity and self-efficacy were increased from 62.09 to 71.03% and from 27.01 to 83.15%, respectively (p < 0.0001). There were no significant differences in the cue to action and perceived benefits and barriers after the intervention. Conclusion The developed model by increasing the motivation of MAIW could remarkably improve the PA level with a decrease in their BMI.

“…This has been demonstrated in research that shows the effect that holding motivation constant has on PBC and SE evaluations (Rhodes & Blanchard, 2007; Rhodes & Courneya, 2003, 2004), as well as in the confounding of motivation with standard SE items, as shown in a recent discriminant content validity study (Burrell, Allan, Williams, & Johnston, 2018). This effect has also been replicated in studies using vignettes, or a small set of instructions to prime participants to consider the literal interpretation of the words ‘can’ and ‘cannot’, and not the figurative interpretations, when completing PBC/SE questionnaires (Lithopoulos, Grant, Williams, & Rhodes, 2020; Rhodes, Williams, & Mistry, 2016). As Williams and Rhodes (2016) concluded, these findings suggest that standard PBC and SE scales are confounded with motivation, and thus, efforts to hold motivation constant should be made.…”

Objectives The objective of this study was to compare standard elicitation techniques for barriers and enablers for physical activity and sleep behaviours, to an alternative approach whereby participants were told to only consider the literal meanings of the words prevent/enable. Design Randomized controlled design. Methods College students were randomized to either a standard methods group (n = 177) (what prevents you from doing behaviour X) or a vignette group (n = 176) to encourage them to think of the literal meaning of the words prevent/enable. Responses were then codified by two blinded researchers. Results Students reported significantly different types of control beliefs between groups. Those in the standard group reported significantly more overall beliefs (p’s < .05, except sleep/enable), suggesting poorer discrimination in interpreting what was meant by ‘prevent’ and ‘enable’. Conclusions This study demonstrates when self‐efficacy‐related control beliefs are elicited, natural language words such as ‘prevent’ and ‘enable’ have the potential to confuse people about the intent of the question.
