“…The overall content validity, face validity, construct validity and internal consistency reliability of the Persian version of the LMUP was supported based on the suggested criteria (11)(12)(13)(14)(15)(16). All the scale's items, with the exception of item 6 (preparation for pregnancy), met the item-to-total correlation criteria to be retained in the translated version.…”

“…However, corrected item-to-total correlation index that represents whether an item in the scale is correlated with the remaining items was used to decide which items could provide meaningful information in explaining the proposed construct. Generally a minimum value of 0.4 is required for corrected item-tototal correlation index of an item to be kept in the scale (15).…”

Research suggests a relatively sizable rate of unintended pregnancies in some subgroups of Iranian women, but there is no concise, standard scale to measure the pregnancy intention of Iranian women. Therefore, the psychometric properties of the Persian version of the London Measure of Unplanned Pregnancy (LMUP) were investigated. The Persian version of the LMUP was tested on randomly selected married women aged 15-49 years in the city of Ajabshir, East Azerbaijan province, north-west of Islamic Republic of Iran. The scale's face validity and internal consistency was examined and its construct validity was tested by exploratory factor analysis. The internal consistency of the scale was acceptable (Cronbach alpha coefficient 0.87). Structural indicators of the Kaiser-MeyerOlkin measure (0.85) and Bartlett test of sphericity (P < 0.001) verified interpretability of the exploratory factor analysis output. Applicability of the Persian version of the LMUP is accepted. Further investigation is needed to understand cultural norms that might influence Iranian women's responses to queries about pregnancy intentions.

“…Regarding internal consistency, it was found that the Cronbach's alpha coefficients (α) values found for the subscale of parental support (α = 0.79) and for the friends' support (α = 0.90) were higher than the minimum value recommended (α greater than 0.70) to define acceptable internal consistency 25 . The same was observed for the values of the CFI.…”

AbstrAct:Objective: To analyze the reliability and validity of a scale used to measure social support for physical activity in adolescents -ASAFA Scale. Methods: This study included 2,755 adolescents (57.6% girls, 16.5 ± 1.2 years of age), from Joao Pessoa, Paraiba, Brazil. Initially, the scale was consisted of 12 items (6 for social support from parents and 6 from friends). The reliability of the scale was estimated by Cronbach's alpha coefficient (α), by the Composite Reliability (CR), and by the model with two factors and factorial invariance by Confirmatory Factor Analysis (CFA) adequacy. Results: The CFA results confirmed that the social support scale contained two factors (factor 1: social support from parents; factor 2: social support from friends) with five items each (one item was excluded from each scale), all with high factor loadings (> 0.65) and acceptable adjustment indexes (RMR = 0.050; RMSEA = 0.063; 90%CI: 0.060 -0.067); AGFI = 0.903; GFI = 0.940; CFI = 0.934, NNFI = 0.932). The internal consistency was satisfactory (parents: α ≥ 0.77 and CR³ ≥ 0.83; friends: α ≥ 0.87 and CR ≥ 0.91). The scale`s factorial invariance was confirmed (p > 0.05; ∆χ 2 and ∆CFI ≤ 0.01) across all subgroups analyzed (gender, age, economic class). The construct validity was evidenced by the significant association (p < 0.05) between the adolescents physical activity level and the social support score of parents (rho = 0.29) and friends (rho = 0.39). Conclusions: The scale showed reliability, factorial invariance and satisfactory validity, so it can be used in studies with adolescents.

“…Additionally, concurrent validity was indicated by significantly positive correlations with good academic adjustment (i.e., academic efficacy) for both the European and the Chinese American samples (see results of zero-order correlations in Table 3). Finally, although there is some disagreement regarding which level of internal consistency is considered acceptable (e.g., [43]), a reliability of .60 or above has been established as acceptable [44]. We averaged the item scores for each scale in this section for further analysis.…”

Training and Adolescent Adjustment among Academically Gifted European and Chinese American Students

Training (jiao xun) has been proposed as an indigenous form of Chinese parenting. Does it exist in other populations? If so, how might it be associated with developmental outcomes? We examined the relationships of training to adolescent academic, psychological, and school adjustment in a sample of 214 Chinese American and 125 European American academically gifted students. We found that training also occurs in European American families with academically gifted children. There were other ethnic similarities: Training was not associated with depression or anxiety in either group, and it was a positive predictor of academic efficacy for both groups. One difference emerged: Training was not associated with school-engagement problems for the European American students, but it was positively associated with fewer school-engagement problems for the Chinese American students. The findings suggest that training has positive implications for academic and school adjustment among academically gifted Chinese American adolescents and for academic adjustment only among their European American peers.
