This study examined test-retest reliability, internal consistency, and construct and predictive validity of the Physical Activity and Nutrition Self-Efficacy (PANSE) scale, an 11-item instrument to assess weight-loss self-efficacy among postpartum women of lower income.
Seventy-one women completed the PANSE scale and psychosocial measures at baseline and at 7 and 13 weeks of a pilot study of weight loss.
Test-retest reliability of PANSE scores was r = 0.55 (P < .01). Cronbach α was r = 0.89. Construct validity was supported by correlations with less-healthful behaviors (r = -0.33, P = .005), perceived stress (r = -0.24, P = .04), and decisional balance (r = 0.25, P = .03). PANSE change scores correlated with intervention group weight changes (r = -0.54, P < .01), although baseline scores did not. One factor emerged (loadings .80 to .57).
The PANSE scale demonstrated adequate reliability, internal consistency, construct validity, and moderate predictive validity. Replication is needed to confirm study findings.
本研究旨在检验 Physical Activity and Nutrition Self-Efficacy（PANSE）量表的重测信度、内部一致性、结构和预测效度，该量表是一种评估低收入产后妇女减肥自我效能的 11 项工具。
71 名妇女在一项减肥初步研究的基线以及 7 周和 13 周时完成了 PANSE 量表和心理社会测量。
PANSE 评分的重测信度为 r = 0.55（P <.01）。克朗巴赫 α 为 r = 0.89。结构效度得到了与更不健康行为（r = -0.33，P =.005）、感知压力（r = -0.24，P =.04）和决策平衡（r = 0.25，P =.03）的相关性的支持。PANSE 变化分数与干预组体重变化相关（r = -0.54，P <.01），尽管基线分数没有。一个因素出现（负荷.80 至.57）。
PANSE 量表显示出足够的信度、内部一致性、结构效度和中等的预测效度。需要进行复制以确认研究结果。
