需要研究开发基于证据的行为干预措施，以预防和治疗精神分裂症人群特有的肥胖。本研究是此类干预研究的先驱，在该研究中，我们检验了健康行动过程方法（HAPA）模型中概述的社会认知的效用，以预测精神分裂症或分裂情感障碍患者的中度至剧烈身体活动（MVPA）意图和行为。采用前瞻性队列设计[基线（T1）、第2周（T2）和第4周（T3）]对101名成人样本（年龄= 41.5±11.7岁；MBMI = 31.2±7.8 kg/m2； 59%为男性）的HAPA结构和MVPA进行了检查。控制年龄、性别、BMI和以前自报的MVPA进行了两次层次回归分析。在第一次回归中，T1时的意向被回归到T1动机HAPA结构（风险感知、情感态度、任务自我效能）和社会支持；在第二次分析中，通过加速度计评估的MVPA状态（符合与不符合MVPA指南）回归到T1社会支持和意图，随后是T2行动和应对计划，以及维持自我效能感。总体而言，动机和社会支持变量占意向方差的28%，情感态度（β = 0.33, p < 0.01）和任务自我效能（β = 0.25, p < 0.05）表现出显著的正相关。对于MVPA状态，整个模型解释了39%的方差，而意志HAPA结构解释了不显著的3%的总方差。这些发现表明，有必要针对这一临床人群的自我效能感和情感态度进行干预。
Research is needed to develop evidence-based behavioral interventions for preventing and treating obesity that are specific to the schizophrenia population. This study is the precursor to such intervention research where we examined the utility of the social cognitions outlined within the Health Action Process Approach (HAPA) model for predicting moderate to vigorous physical activity (MVPA) intentions and behavior among individuals with schizophrenia or schizoaffective disorder. A prospective cohort design [baseline (T1), week 2 (T2), and week 4 (T3)] was used to examine the HAPA constructs and MVPA across a sample of 101 adults (Mage = 41.5 ± 11.7 years; MBMI = 31.2 ± 7.8 kg/m2; 59% male). Two hierarchical regression analyses were conducted controlling for age, gender, BMI, and previous self-reported MVPA. In the first regression, intentions at T1 were regressed onto the T1 motivational HAPA constructs (risk perception, affective attitudes, task self-efficacy) and social support; MVPA status (meeting vs. not meeting the MVPA guidelines) assessed via accelerometry at T3 was regressed onto T1 social support and intentions followed by T2 action and coping planning, and maintenance self-efficacy in the second analysis. Overall, the motivational and social support variables accounted for 28% of the variance in intentions, with affective attitudes (β = 0.33, p < 0.01) and task self-efficacy (β = 0.25, p < 0.05) exhibiting significant, positive relationships. For MVPA status, the model as a whole explained 39% of the variance, with the volitional HAPA constructs explaining a non-significant 3% of this total variance. These findings suggest a need for interventions targeting self-efficacy and affective attitudes within this clinical population.
