Despite the fairly widespread adoption of the 10-item Purdue Pharmacist Directive Guidance Scale (PPDG) over the last decade, only one study has assessed its psychometric properties. The present study examined the validity and reliability of the scale in a sample of 99 diabetic patients in the Southwestern United States. Principal axis factor analysis with Varimax rotation yielded two factors, “Instruction” and “Feedback and Goal Setting,” similar to those found when the scale was originally developed. Cronbach's alphas for the total scale and the two factors were 0.95, 0.95, and 0.92, respectively. The scale and the two factors correlated significantly and positively with number of visits by patients to the pharmacist in the past 3 mo. These results provide further evidence for the internal consistency, and construct and criterion-related validities of the scale.

There are few instruments with good validity and reliability for evaluating body image in children. In this study we aimed to develop and evaluate the psychometric properties of a scale for Brazilian children. In Study 1, we developed 53 items on the basis of a literature review, previous body image scales and qualitative study. We developed the item format and response options and developed instructions for both researchers and participants. In Study 2, we used 10 experts and 21 boys and girls aged 7–11 years ( M = 8.25 years, SD = 1.70) to evaluate item content and semantics. The scale went through further refinement, leading to the exclusion of some items and the modification of others. In Study 3, we analyzed the instrument’s psychometric properties in 571 girls ( M = 9.17 years of age, SD = 1.23) and 597 boys ( M = 9.32 years, SD = 1.24) from all over Brazil, using exploratory and confirmatory factorial analyses with independent samples. The scale’s final version for females was composed of 17 items divided into five factors; and the final male version included 13 items and two factors. Both versions presented satisfactory convergent and discriminant validity, and these scales can now be used reliably with 7-11 year old Brazilian children.

Psychometric Properties of The Greek Version of the Test of Performance Strategies-Competition Scale (TOPS-CS)The aim of the present study was to examine the psychometric properties of the Test of Performance Strategies-Competition scale (TOPS-CS; Thomas et al., 1999) in Greek athletic population. The TOPS-CS was designed to assess eight psychological strategies used by athletes in competition (activation, automaticity, emotional control, goal-setting, imagery, negative thinking, relaxation and self-talk). In order to evaluate the psychometric properties of the inventory, two different research studies were conducted in two different age groups (n1=382 athletes, aged 16 to 20 years and n2=343 athletes, aged 12 to 15 years). Furthermore, 263 athletes, (aged 16 to 20 years) completed the TOPS-CS, purposing to perform confirmatory factor analysis. The results of the first study supported the initial factorial structure of the TOPS-CS for athletes aged 16-20 years. Reliability analysis also provided adequate evidence for the internal consistency and stability of the scale for Greek athletes of this age. However, for athletes aged 12 to 15 years, the validity and reliability of the inventory were questionable and further research is required.

Abstract Background Diabetic foot self-care refers to a group of self-management behaviors that can reduce the incidence of foot ulcers and amputations. It is necessary to have a valid and reliable standard tool to measure foot self-care in diabetic patients. This study aimed to evaluate the psychometric properties of the Persian version of the Diabetic Foot Self-Care Questionnaire of the University of Malaga, Spain (DFSQ-UMA) in Iran. Methods This cross-sectional study was conducted with 407 diabetic patients who were selected using a convenient sampling method. Construct validity was assessed by exploratory (with 207 patients) and confirmatory (with 200 patients) factor analyses. Internal consistency was calculated using Cronbach’s alpha and McDonald’s omega coefficients. Results In the exploratory factor analysis, three factors with eigenvalues of 3.84, 2.41, and 2.26 were extracted that together explained 56.74% of the total variance of diabetic foot self-care. A Cronbach’s alpha of 0.865 was found for the total instrument. Conclusions The Persian version of the DFSQ-UMA has good validity and reliability, and given its good psychometric properties, it can be used in future studies.

Validity And Reliability

Abstract Aims. - This research aimed at designing and psychometric properties of a questionnaire for health-worker skills evaluation to obtain a self-care program for pre-diabetic patients. Materials. - The questionnaire items were first developed, utilizing reliable and specialized sources involving papers and scientific books and interviews with experts and specialists in diabetes and health education. The questionnaire's psychometric properties were evaluated utilizing face validity, content validity, construct validity, internal consistency, and stability. Results. - Due to the results of investigating the texts and interviews, the initial questionnaire, including 54 phrases, was presented. In the face validity section, eight expressions were removed quantitatively. Then, in identifying content validity, three other words were deleted, and the questionnaire was reduced to 43 phrases in general. This questionnaire's exploratory factor analysis revealed four factors involving self-efficacy, attitude, reinforcing factors, and enabling factors. These four factors explained 57.51% of the total variance of the test. The results of the confirmatory factor analysis also confirmed the factors of the PRECEDE-PROCEED model. Cronbach's alpha and intra-cluster correlation index for questionnaire structures ranged from 0.87-0.88 and 0.87-0.88, respectively. Conclusion. - The designed questionnaire has good validity and reliability. It can be said that this questionnaire is a suitable and usable tool for prediabetes in similar research to evaluate health worker skills in obtaining a self-care program for prediabetes.

Physical and cognitive factors contribute to independence in daily activities, but the confidence to perform an activity (self-efficacy) also contributes to it. The purpose of this study was to assess the psychometric properties of the Task Self-efficacy Scale (TSE) for confidence in performing daily activities. Validity and reliability were assessed in 278 older adults with scores on all items on the TSE for analysis. Factor analysis revealed two factors (self-care and mobility) explaining 72.42% of the variance in the items. Moderate to large correlations were found between the TSE for Self-Care and TSE for Mobility to exertion (.90 to .93, respectively) and fatigue (–.79 to –.84, respectively) associated with activities assessed in the TSE. The expected differences in TSE were found between those with and without mobility difficulties, fear of falls, and shortness of breath with activity. Cronbach’s alpha was .96.

Two Factors

The article aims to study the arrival of coffee to Mexico and Chiapas and to analyze how coffee production increased in the southern state, thanks to two factors: the cheapness of land and the arrival of foreign investment, mainly from the United States and from Germany. The hypothesis of this work is that the increase in coffee production in Chiapas, between1893-1920, was due to the sale of land at cheap prices and the arrival of foreign investment essentially of German and American origin. The methodology used was the historical one. This type of research seeks to reconstruct the past in the most objective and exact way possible, through examining documents and periods of the past. This method, instead of directly observing facts, acts indirectly by studying documents and newspapers, in this particular case we rely on Mexican and American newspapers of the time. It is concluded that Chiapas positioned itself as one of the main coffee producing states in the country due to two reasons: the low cost of land to plant and the arrival of foreign investment.

During the first years of this century an astronomer, Dr A. E. Douglass, started a series of examinations of the annual increment in trees just south of Flagstaff, Arizona, to see if the cyclical nature of sun-spot appearances was reflected in tree growth, through their influence on climate. He found that there was a rather high correlation between tree growth and sun-spots in the living trees he examined. In order to extend his studies into the past—beyond the 500 years recorded by living trees—he collected material taken from beams in the old Spanish Missions that dot the southwestern United States. He had found that it was possible to identify certain characteristic sequences of tree-ring widths with certain years, and thus project into the past his chart of tree growth from timbers cut at an unknown past date. In doing so he discovered a technique that has founded a new branch of science—dendrochronology.

Community Dwelling Older Adults

This current study investigated the construct validity and reliability of the Geriatric Fear of Falling Measure (GFFM) among community-dwelling older adults in the United States. Eighty-eight participants were assessed on the GFFM together with demographics, falls, and fear of falling and falls-efficacy measures at baseline and an 8-week follow-up visit. Cronbach’s alpha, regression analyses, and correlation analyses were used to examine the psychometric properties of the GFFM. The results showed that the GFFM demonstrated good construct validity and reliability among community-dwelling older adults in the United States. Our findings provide evidence for the validity and reliability of the GFFM. Further study with a larger and diverse sample is needed to determine whether the GFFM has potential as a quick screening tool of fear of falling in clinical settings.

The Revised Piper Fatigue Scale (R-PFS) is an instrument designed to measure subjective fatigue that was developed in samples with physical illness. Its psychometric properties in nonclinical samples are unknown. The purpose of this study was to examine the psychometric properties of the R-PFS in a sample of caregivers of stroke survivors. The convenience sample of 132 caregivers was primarily women (74%), White (71%), college-educated (73%), and employed (52%), with a mean age of 56.7 years (SD = 13.71). Internal consistency reliabilities for the four R-PFS subscales and the total scale were excellent, ranging from .90 to .97. Principal axis factor analysis with oblique rotation was conducted to examine construct validity of the R-PFS. A three-factor solution explained 75.9% of the common variance. Two factors totally replicated the behavioral/severity and affective meaning subscales of the R-PFS. The third factor incorporated a combination of Piper’s sensory and cognitive/mood subscales and appeared to summarize how fatigue makes the caregiver feel. The R-PFS demonstrated strong internal consistency reliability and construct validity in this sample. However, data suggest that caregivers may perceive certain feelings associated with fatigue as conceptually similar when these feelings are conceptually distinct in Piper’s breast cancer sample. The study supports the need for psychometric evaluation of instruments developed in clinical populations prior to their use in nonclinical populations.
