Item Effectiveness of a Physical Activity Promotion Program on Perceived Self-efficacy, Physical Activity and Physical Fitness among Thai Adolescent Girls(The Thailand Nursing Council, 2010-03-30) Narumon Teerarungsikul; Rutja Phuphaibul; Carol J. Loveland-Cherry; Renu Pookboonmee; Kallaya Kijboonchoo; Dechavudh NityasuddhiThe purpose of this quasi-experimental study was to investigate the outcomes of a physical activity promotion program on perceived self-efficacy, physical activity and physical fitness among Thai adolescent girls. The study sample was recruited from grades seven and eight in two public schools in Chonburi province, Thailand. Simple random assignment was used to assign students from one school as the experimental group and students from the other school as the control group. Both groups received general information on physical activity. However, the experimental group also received the physical activity promotion program based on Pender’s Health Promotion Model and Bandura’s Self-efficacy Theory. Data were collected at baseline, on the eighth week when the intervention ended, and on the 12th week. The results revealed that, by the eighth week, the experimental group’s scores for perceived self-efficacy, physical activity and light activity were significantly higher than those of the control group. However, these effects could not be maintained by the 12th week. Furthermore, the physical fitness scores were not significantly different between the experimental and control groups at the eighth and 12th weeks. The findings suggest the program resulted in short-term enhanced perceived self-efficacy and physical activity, among Thai adolescent girls, at eight weeks post-intervention. Therefore, implementation of this program to promote perceived self-efficacy and physical activity, among adolescent girls in school, is encouraged since the students became interested and active in participating in the activities. However, this program should be further developed to sustain changes in perceived self-efficacy and physical activity, including increased physical fitness.Item Physical Activity Questionnaire Development and Testing among Elderly Community-Dwelling Thais(The Thailand Nursing Council, 2010-03-30) Vanida Visuthipanich; Yupapin Sirapo-ngam; Porntip Malathum; Kallaya Kijboonchoo; Thavatchai Vorapongsathorn; Kerri M. Winters-StoneThis descriptive cross-sectional research aimed to develop and test a self-report physical activity questionnaire (SPAQ) among elderly community-dwelling Thais. The study involved two phases. Phase I, questionnaire development, consisted of six steps: 1) defining the concept; 2) generating an item pool; 3) defining the choices of responses to items; 4) reviewing items; 5) conducting a pilot study; and, 6) selecting items for analyses. Inter-rater agreement and item-level for content validity index for the first draft of the SPAQ (47 items) were .99 and .89, respectively. Face validity was conducted with the second draft of the SPAQ (48 items). A pilot study, based on the dimensions, household, occupation, leisure time, and transportation, was conducted with the third draft (77 items). To obtain the final draft of the instrument (55 items), content categorization of activities was conducted with the third draft of the SPAQ, based on the literature’s descriptions of the dimensions of physical activity and the deletion of items participants, in the pilot study, did not perform. Phase II, psychometric property evaluation, used Pearson’s correlation coefficient to analyze the concurrent validity, predictive validity and test-retest reliability. An acceptable concurrent validity coefficient was obtained by examining a relationship between the SPAQ and Actigraph readings. The SPAQ presented good predictive validity, as indicated by its correlation with the six minute walk test. However, a non-significant correlation between the SPAQ and both physical function and body fat was found. The 7-day test-retest reliability coefficient of the SPAQ indicated good reliability. Although the concurrent validity presented a modest coefficient, the SPAQ was shown to be relatively convenient, simple and suitable for administration. These results were similar to those found among Western populations.Item Validity and Reliability of the Modified Thai Adolescent’s Physical Activity Questionnaire(Thailand Nursing and Midwifery Council, 2010-04-03) Pissamai Wattanasit; Ladawan Prateepchaikul; Wongchan Petpichetchian; Janet C. Meininger; Kallaya KijboonchooThis study sought to determine the validity and reliability of a self-report instrument, the Modified Thai Adolescent’s Physical Activity Questionnaire (MTAPAQ). Concurrent validity was assessed using 40 secondary school Thai adolescents (17 males and 23 females), who wore an ActiGraph accelerometer, during their waking hours for seven consecutive days. The students completed the MTAPAQ upon completion of the recording period. Reliability was evaluated using 30 secondary school Thai adolescents (12 males and 18 females) who completed the MTAPAQ by recalling their physical activities during the previous seven days, on two separate occasions that were three days apart.A significant correlation was found between the Metabolic Equivalent of Tasks (MET-mins), as determined by the MTAPAQ, and log (10) transformed activity counts, as determined by the ActiGraph accelerometer. The test-retest reliability, of the two administrations of the MTAPAQ, was found to be significant. The findings provide evidence of an acceptable level of concurrent validity and test-retest reliability of the MTAPAQ for use with Thai adolescents.
