Despite the fact that improved health, social, and economic situations have significantly affected the reduction of its infestation, pediculosis is still spreading worldwide.
This study is conducted to evaluate the explanatory power of health belief model constructs in adoption of preventive pediculosis infestation behavior in female primary school students.
This study involves two stages. First, a cross-sectional study was conducted. In the second stage, a quasi-experimental intervention was performed. One hundred eighty female elementary school students in Omidiyeh County were randomly selected in two 90-subject groups (experimental and control). Samples were matched in two groups in terms of demographic variables. A group of educational intervention was based on the most effective construct of the first stage; and the educational intervention of control group was based on the low-effective construct. The path analysis and LISREL 8.5 software was utilized to compare the fit and the variance cover percentage of adopting preventive pediculosis infestation behaviors.
According to the pre-intervention findings, there was no significant difference between experimental and control groups in terms of factors affecting the adoption of preventive pediculosis infestation behavior. This model had a weaker fit in the experimental than the control group, but these indices had better status after intervention in the experimental than the control group. Meanwhile, the cover percentage of explained variance for the experimental group after educational intervention was higher than pre-intervention, but it was lower in the control group. Finally, health belief model constructs (including the knowledge, cue to action, perceived susceptibility and severity, perceived benefits and barriers, and self-efficacy) in the experimental group, had better fit after the educational intervention compared with pre-intervention.
Efficiency of the health belief model was approved for adopting preventive pediculosis infestation behavior in female primary school students. The future intervention studies should utilize the structural equation modeling approach separately in experimental and control groups to compare the changes in behavior between different demographic groups in the field of pediculosis infestation behavior.
尽管健康、社会和经济状况的改善对减少虱病感染产生了显著影响，但虱病仍在全球范围内传播。
本研究旨在评估健康信念模型构建因素对小学女生采取预防虱病感染行为的解释力。
本研究分为两个阶段。首先进行横断面研究。在第二阶段，进行了准实验干预。在奥米迪耶县随机选取180名小学女生，分为两个各90人的组（实验组和对照组）。两组在人口统计学变量方面进行了匹配。一组教育干预基于第一阶段最有效的构建因素；对照组的教育干预基于效果较差的构建因素。利用路径分析和LISREL 8.5软件比较采取预防虱病感染行为的拟合度和方差覆盖率。
根据干预前的结果，实验组和对照组在影响采取预防虱病感染行为的因素方面没有显著差异。该模型在实验组中的拟合度低于对照组，但在实验组干预后的这些指标状况优于对照组。同时，实验组教育干预后的解释方差覆盖率高于干预前，但对照组则较低。最后，实验组的健康信念模型构建因素（包括知识、行动线索、感知易感性和严重性、感知益处和障碍以及自我效能）在教育干预后与干预前相比拟合度更好。
健康信念模型在小学女生采取预防虱病感染行为方面的有效性得到了证实。未来的干预研究应在实验组和对照组中分别采用结构方程建模方法，以比较不同人口统计学群体在虱病感染行为领域的行为变化。
