Having condoms available has been shown to be an important predictor of condom use. We examined whether or not personal norm and goal enjoyment contribute to predicting having condoms available in the context of cognition specified by the theory of planned behaviour (TPB).
Prospective survey study, with a baseline and follow-up measurement (at 3 months).
Data were gathered using an online survey. In total 282 adolescents (mean age = 15.6, 74% female adolescents) completed both questionnaires. At baseline, demographics, sexual experience, condom use, TPB variables, descriptive norm, personal norm, and enjoyment towards having condoms available were measured. At T2 (3 months later) having condoms available was measured. Direct and moderating effects of personal norm and goal enjoyment were examined by means of hierarchical linear regression analyses.
Regression analyses yielded a direct effect of self-efficacy and personal norm on condom availability. In addition, moderation of the intention-behaviour relation by goal enjoyment added to the variance explained. The final model explained approximately 35% of the variance in condom availability.
Personal norm and goal enjoyment add to the predictive utility of a TPB model of having condoms available and may be useful intervention targets.
What is already known about this subject? Having condoms available is an important prerequisite for actual condom use. The theory of planned behaviour has successfully been applied to explain condom availability behaviour. The theory of planned behaviour has been criticized for not adequately taking into account affective motivation. What does this study add? Personal norm and goal enjoyment add to the predictive utility of the model. Personal norm explains condom availability directly, enjoyment increases intention enactment. Personal norm and goal enjoyment therefore are useful intervention targets.
有研究表明,安全套的可获得性是预测安全套使用的一个重要因素。我们检验了在计划行为理论(TPB)所规定的认知背景下,个人规范和目标享受是否有助于预测安全套的可获得性。
前瞻性调查研究,基线和随访测量(3 个月)。
使用在线调查收集数据。共有 282 名青少年(平均年龄=15.6,74%为女性青少年)完成了两份问卷。在基线时,测量了人口统计学、性经验、安全套使用、TPB 变量、描述性规范、个人规范和获得安全套的享受程度。在 T2(3 个月后),测量了获得安全套的情况。通过分层线性回归分析,检验了个人规范和目标享受的直接和调节作用。
回归分析得出,自我效能感和个人规范对安全套的可获得性有直接影响。此外,目标享受对意图-行为关系的调节作用增加了可解释的方差。最终模型解释了安全套可获得性约 35%的方差。
个人规范和目标享受增加了 TPB 模型对安全套可获得性的预测效用,可能是有用的干预目标。
关于这个主题,已经知道了什么?安全套的可获得性是实际使用安全套的重要前提。计划行为理论已成功地应用于解释安全套可获得性行为。计划行为理论因未能充分考虑情感动机而受到批评。这项研究增加了什么?个人规范和目标享受增加了模型的预测效用。个人规范直接解释了安全套的可获得性,享受增加了意图的实施。因此,个人规范和目标享受是有用的干预目标。
