The aim of the present study was to validate the Lifestyle Behavior Checklist (LBC) questionnaire, to measure Iranian parents' perceptions of their children's weight-related behaviors and their self-efficacy in dealing with those behaviors.
The LBC was translated into Farsi. Face and content validity of the questionnaire was evaluated by an expert panel. A total of 213 mothers of 3-12-year-old children responded to the questionnaire. Criterion validity of the questionnaire was evaluated through comparing its result with a parenting style questionnaire. Principal component analysis (PCA) and confirmatory factor analyses (CFA) were used to evaluate construct validity of the questionnaire. Reproducibility was measured by twice administration of LBC, one month apart and using Spearman's rho correlation test. The questionnaire's internal consistency was assessed by calculating Cronbach's α.
LBC Problem scale was significantly correlated with authoritarian parenting style score, while the Confidence scale was significantly correlated with authoritative and negatively with permissive and authoritarian parenting styles. PCA suggested a six-factor construct, including, fussy eating, food-related problem behaviors, overeating behaviors, low interest in physical activity, poor self-image and sedentary behaviors. The results of CFA indicated acceptable fit indices for the proposed models. Both, Problem scale (Cronbach's α = 0.8) and Confidence scale (Cronbach's α = 0.95) had high internal consistency. Spearman correlation coefficients indicated acceptable reproducibility for both the Problem scale (r = 0.74) and the Confidence scale (r = 0.70).
The Farsi version of LBC questionnaire is reliable and reasonably valid to measure Iranian mothers' perception of their children's weight-related problem behavior.
本研究旨在验证生活方式行为检查表（LBC）问卷，以测量伊朗父母对其子女与体重相关行为的看法及其处理这些行为的自我效能感。
LBC 被翻译成波斯语。问卷的表面效度和内容效度由专家小组评估。共有 213 名 3-12 岁儿童的母亲对问卷做出回应。通过将问卷结果与养育风格问卷进行比较来评估问卷的效标效度。主成分分析（PCA）和验证性因子分析（CFA）用于评估问卷的结构效度。通过间隔一个月两次进行 LBC 并使用斯皮尔曼 rho 相关检验来测量重复性。使用 Cronbach's α 评估问卷的内部一致性。
LBC 问题量表与专制养育风格得分显著相关，而信心量表与权威养育风格显著相关，与放任和专制养育风格显著负相关。PCA 提示了包括挑食、与食物相关的问题行为、过度进食行为、对身体活动缺乏兴趣、不良自我形象和久坐行为在内的六因素结构。CFA 的结果表明，所提出模型的拟合指数可接受。问题量表（Cronbach's α=0.8）和信心量表（Cronbach's α=0.95）的内部一致性均较高。Spearman 相关系数表明问题量表（r=0.74）和信心量表（r=0.70）的重复性可接受。
LBC 问卷的波斯语版本可靠且具有相当的有效性，可用于衡量伊朗母亲对其子女与体重相关的行为问题的看法。
