“…and the descriptive fit values (Muth6n, 1989a), 0.002 and 0.001, for Baltimore and Durham-Piedmont, respectively, also indicate good model fit. The covariance structure of the symptom level data from the two sites was consistent with a single factor, as evidenced by a scree plot of eigenvalues (not shown; Cattell, 1965;Edelbrock, 1987;Gibbons, Clark, Cavanaugh, & Davis, 1985).…”

“…Principle axis factoring analysis generated a four-factor that accounted for 72% of the variance in psychosocial items. A factor loading greater than 0.35 was stated as loading threshold using the rule of maintaining factors with Eigen values greater than 1.0 (Gibbons, Clark, Cavanaugh, & Davis, 1985). Barlett Sphericity test was statistically significant, x2(595) =19502.704, p =.000, the variables were highly correlated to one another.…”

Breast cancer is the most widespread cancer among women worldwide. The success of breast cancer screening initiatives depends on the target women and their attitudes. The aim of this study is to develop an instrument for the understanding of women's socio-psychological factors in relation to mammography screening. The study is exploratory in nature and combines three theories. These theories include the health belief model (HBM), theory of reasoned action (TRA) and the social cognitive theory. The purpose of the inquiry is to examine the behavioural and socio-psychological factors inspiring women participation in mammography screening.A five level Likert scale was employed to discover factors influencing women participation in mammography. Self-administered questionnaire was developed and modified based on previous literatures. A total of 400 women aged 35-69 years, were randomly selected. The study was conducted among female clients of maternity hospitals affiliated to Medical Sciences of Tehran University, Tehran, Iran.Principal Components Analysis was applied to describe the psychometric evaluation of the instruments measuring self efficacy, beliefs, social influence and barriers. Principle axis factorization generated four factors that accounted for 72% in the variance of psychosocial items.The reliability of the data and scale was computed with Cronbach's Alpha. The values were 0.993, 0.850, 0.709 and 0.952 for self efficacy, beliefs, social influence and barriers respectively. The alpha values exceeded 0.70 suggested as acceptable inter-item reliability threshold, indicating high correlation among the variables in the data set. Consequently, the sets of items yielded results consistent with the complete instrument.However, the current study differed from other studies with respects to the number of factors found. In line with the above, questions that load on each factor and the amount of variance accounted for in each factor should be compared in future studies.Indeed, the findings of the study contributed to the knowledge of the psychometric properties in breast cancer screening instruments, particularly in the utilization of mammography which is needed to asses for other Asian women in future study.

“…However, item response theory (IRT) [Embretson and Reise, 2000;Hambleton and Swaminathan, 1985] analysis was emphasized, as it allows for more explicit, theory-based tests of these group differences. This framework was previously used by our group [Rush et al, 2006;Trivedi et al, 2004b] and by others [Bech et al, 1978[Bech et al, , 1981Gibbons et al, 1985;Evans et al, 2004] to study depression. The results of the IRT and CTT analyses are usually complementary.…”

Symptom features of postpartum depression: are they distinct?

The clinical features of postpartum depression and depression occurring outside of the postpartum period have rarely been compared. The 16-item Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR 16 ) provides a means to assess core depressive symptoms. Item response theory and classical test theory analyses were conducted to examine differences between postpartum (n 5 95) and nonpostpartum (n 5 50) women using the QIDS-SR 16 . The two groups of females were matched on the basis of age. All met DSM-IV criteria for nonpsychotic major depressive disorder. Low energy level and restlessness/ agitation were major characteristics of depression in both groups. The nonpostpartum group reported more sad mood, more suicidal ideation, and more reduced interest. In contrast, for postpartum depression sad mood was less prominent, while psychomotor symptoms (restlessness/agitation) and impaired concentration/decision-making were most prominent. These symptomatic differences between postpartum and other depressives suggest the need to include agitation/restlessness and impaired concentration/decision-making among screening questions for postpartum depression.
