“…The most frequently self-reported study limitations included a lack of generalisability due to the homogeneity and/or size of the sample [6, 10, 13, 23, 24, 30-33, 35, 36, 47], the possibility of social desirability bias [6,10,23,24,30,[32][33][34][35][36]47], and the self-report nature of data collection [6,24,25,32,35,36,38]. Other limitations relating to sampling included convenience sampling [31,34,47] and the possibility of participation bias, whereby only those who thought the study was relevant to them (e.g., those who drink alcohol) may have chosen to participate [35]. Study design limitations mentioned included the correlational or cross-sectional study design [25], the heterogeneity of focus group membership [10], high attrition rate and short followup [47] and the fact that only some parts of an intervention were evaluated [30,47].…”
