We assess the association between conscientiousness and adherence to the oral contraceptive pill (OCP), and examine if such a relationship is independent of a measure of prospective memory and a range of social cognitive variables.
Data were collected from 150 OCP users at baseline, and 99 provided follow-up data four weeks later. Conscientiousness, a range of social cognitive predictors and prospective memory were assessed at baseline. OCP adherence was measured at baseline, and again at Time 2. Data were analysed using correlation and multiple linear regression.
Higher conscientiousness was associated with higher overall OCP adherence in both cross-sectional (r = -0.28, p < 0.01) and prospective analysis (r = -0.34, p < 0.01). Conscientiousness predicted OCP adherence at Time 2, adjusting for OCP adherence at Time 1 (R(2) change = 0.02, p = 0.04). The association was reduced to non-significance when social cognitive predictors and prospective memory were included in the multivariable model. Prospective memory was an independent predictor of OCP adherence at Time 2.
This is the first study to identify an association between conscientiousness and OCP adherence. The association is not independent from social cognitive predictors and prospective memory. Facet-level analysis of conscientiousness and formal mediation analyses are recommended in future replications.
我们评估尽责性与口服避孕药（OCP）依从性之间的关联，并检验这种关系是否独立于前瞻性记忆测量指标和一系列社会认知变量。
在基线时从150名口服避孕药使用者中收集数据，四周后99人提供了随访数据。在基线时评估尽责性、一系列社会认知预测指标和前瞻性记忆。在基线时以及第二次随访时测量口服避孕药的依从性。使用相关性分析和多元线性回归对数据进行分析。
在横断面分析（r = -0.28，p < 0.01）和前瞻性分析（r = -0.34，p < 0.01）中，较高的尽责性均与较高的口服避孕药总体依从性相关。尽责性可预测第二次随访时的口服避孕药依从性，对第一次随访时的口服避孕药依从性进行校正后（R²变化 = 0.02，p = 0.04）。当多变量模型中纳入社会认知预测指标和前瞻性记忆时，这种关联减弱至无统计学意义。前瞻性记忆是第二次随访时口服避孕药依从性的独立预测指标。
这是第一项确定尽责性与口服避孕药依从性之间存在关联的研究。这种关联并非独立于社会认知预测指标和前瞻性记忆。建议在未来的重复研究中进行尽责性的层面分析和正式的中介分析。
