Development and psychometric evaluation of the Thai Human Papillomavirus Beliefs Scale

Abstract

In this study, we developed and evaluated the psychometric properties of the Thai Human Papillomavirus Beliefs Scale. The Scale was tested on 386 young women aged 18-24 years in Chiang Mai, Thailand. Content validity of the Scale was evaluated by a panel of experts, construct validity was determined using exploratory factor analysis, and reliability was assessed for stability and internal consistency. Factor analysis provided empirical support for the existence of four factors, which accounted for 67.7% of the total variance: perceived susceptibility, perceived seriousness, perceived benefits, and perceived barriers. Cronbach's α reliability coefficients for the four subscales ranged from 0.59 to 0.86. Factors predicting intention to receive the papillomavirus vaccine were perceived susceptibility, perceived benefits, and perceived barriers. The Thai Human Papillomavirus Beliefs Scale demonstrated promising psychometric properties, indicating that it might be a useful instrument for assessing young women's human papillomavirus and cervical cancer-associated beliefs, and for predicting human papillomavirus vaccination intention.

Parental acceptance of HPV vaccines in Chiang Mai, Thailand

“…In the fourth part, the Thai Human Papillomavirus Beliefs Scale (THPVBS) was used to measure participants’ beliefs about HPV vaccination. The THPVBS was originally developed by Juntasopeepun et al . to assess young adults’ beliefs about HPV and cervical cancer; in the present study, a modified scale including 12 THPVBS items was applied.…”

To Consent or Decline HPV Vaccination: A Pilot Study at the Start of the National School‐Based Vaccination Program in Sweden

“…The questionnaire was specifically developed for this study. It was based on earlier studies 8,9,13,34 and clinical experience and comprised 46 questions grouped into 6 areas: (1) demographics of the participants and acceptance of previous childhood vaccinations and the vaccine against influenza A (H1N1); (2) beliefs about other vaccinations; (3) beliefs about the information provided about the HPV vaccination; (4) knowledge about HPV and HPV vaccine; (5) beliefs concerning sexual behavior; and (6) beliefs regarding HPV and the HPV vaccination based on the HBM constructs (benefits, barriers, severity, susceptibility, and cues to action). Cues to action comprised questions about the decision-making process.…”
