Misperception of Norms About Intimate Partner Violence as a Driver of Personal IPV Attitudes and Perpetration: A Population-Based Study of Men in Rural Uganda.

Intimate partner violence (IPV) against women is a global public health problem. Conceptual frameworks suggest misperceived norms around IPV might drive perpetration of violence against women in southern and eastern Africa. We conducted a cross-sectional, population-based survey of all men residing in a rural parish in southwest Uganda, eliciting their endorsement of IPV in five hypothetical scenarios and their reported frequency of perpetration of violence against their wife/main partner. They also reported their perceptions about the extent to which most other men in their villages endorsed and/or perpetrated IPV, which we compared against the population data to measure the primary explanatory variable of interest: whether individuals misperceived norms around IPV. We fitted multivariable Poisson regression models specifying personal IPV endorsement and IPV perpetration as the outcomes. Overall, 765 men participated in the study (90% response rate): 182 (24%) personally endorsed IPV, and 78 of 456 partnered men (17%) reported perpetrating one or more acts of IPV at least once per month. Although most men neither endorsed nor reported perpetrating IPV, 342 (45%) men mistakenly thought that most other men in their villages endorsed IPV and 365 (48%) men mistakenly thought that most other men perpetrate IPV at least monthly. In multivariable regression models, men who misperceived most men to endorse IPV were more likely to endorse IPV themselves (adjusted relative risk [aRR] = 2.44; 95% CI [1.66, 3.59]; p < .001). Among partnered men, those who misperceived IPV perpetration to be normative were more likely to perpetrate IPV themselves (aRR = 4.38; [2.53, 7.59]; p < .001). Interventions to correct misperceived norms about IPV may be a promising method for reducing violence against women in rural Uganda.

Cigarette smoking and misperceived norms among adults in rural Uganda: a population-based study.

BACKGROUND: Little is known about perceived norms about cigarette smoking in Uganda or the extent to which perceptions drive personal cigarette smoking behaviour. METHODS: We conducted a cross-sectional study in 2016-2018 that targeted all adults who resided within eight villages in Rwampara District, southwestern Uganda. Personal cigarette smoking frequency was elicited by self-report. We also asked participants what they believed to be the cigarette smoking frequency of most other adult men and women in their villages (i.e., perceived norms). Frequent cigarette smoking was defined as 4+ times/week. We compared perceived norms to cigarette smoking frequency reports aggregated at the village level. We used multivariable Poisson regression to estimate the association between perceived norms and personal cigarette smoking behaviour. RESULTS: Among 1626 participants (91% response rate), 92 of 719 men (13%) and 6 of 907 women (0.7%) reported frequent smoking. However, 1030 (63%) incorrectly believed most men in their villages smoked cigarettes frequently. Additionally, 116 (7%) incorrectly believed that most women in their villages smoked cigarettes frequently. These misperceptions were pervasive across social strata. Men who misperceived frequent cigarette smoking as the norm among other men in their villages were more likely to smoke frequently themselves (adjusted relative risk=1.49; 95% CI, 1.13 to 1.97). CONCLUSIONS: Most adults overestimated cigarette smoking frequency among village peers. Men who incorrectly believed that frequent smoking was the norm were more likely to engage in frequent smoking themselves. Applying a 'social norms approach' intervention by promoting existing healthy norms may prevent smoking initiation or motivate reductions in smoking among men in rural Uganda.
