A Comparison of the Pittsburgh Sleep Quality Index, a New Sleep Questionnaire, and Sleep Diaries

A Comparison of the Pittsburgh Sleep Quality Index, a New Sleep Questionnaire, and Sleep Diaries

Date: August 2012
Creator: Sethi, Kevin J.
Description: Self-report retrospective estimates of sleep behaviors are not as accurate as prospective estimates from sleep diaries, but are more practical for epidemiological studies. Therefore, it is important to evaluate the validity of retrospective measures and improve upon them. The current study compared sleep diaries to two self-report retrospective measures of sleep, the commonly used Pittsburgh Sleep Quality Index (PSQI) and a newly developed sleep questionnaire (SQ), which assessed weekday and weekend sleep separately. It was hypothesized that the new measure would be more accurate than the PSQI because it accounts for variability in sleep throughout the week. The relative accuracy of the PSQI and SQ in obtaining estimates of total sleep time (TST), sleep efficiency (SE), and sleep onset latency (SOL) was examined by comparing their mean differences from, and correlations with, estimates obtained by the sleep diaries. Correlations of the PSQI and SQ with the sleep diaries were moderate, with the SQ having significantly stronger correlations on the parameters of TST, SE, and sleep quality ratings. The SQ also had significantly smaller mean differences from sleep diaries on SOL and SE. The overall pattern of results indicated that the SQ performs better than the PSQI when compared to sleep ...

Relation Between the FITNESSGRAM® Ftness Assessment and Self-Reported Physical Activity Questions

Relation Between the FITNESSGRAM® Ftness Assessment and Self-Reported Physical Activity Questions

Date: August 2011
Creator: Tucker, Jacob
Description: The FITNESSGRAM® is regularly used to assess physical fitness (PF) of adolescents. In addition to the PF assessment, the FITNESSGRAM also includes self-report physical activity (PA) items. The purpose of this study was to examine whether the self-report aerobic, muscular strengthening, and flexibility PA behavior items indicated adolescents’ cardiorespiratory, muscular strength, and flexibility fitness and their body composition. Logistic regression analysis was used to examine the relation between the amount of PA and PF status. Adolescents not meeting the recommended PA amount had significantly higher odds of not achieving a healthy fitness status. Meeting the recommended PA amount was associated with achieving healthy PF status. Thus, adolescents’ amounts of aerobic, muscular strengthening, and flexibility PA were an indication of their corresponding health-related PF standard.

Relationship of the PDI Employment Inventory Scales to Criminal Behaviors

Relationship of the PDI Employment Inventory Scales to Criminal Behaviors

Date: August 2005
Creator: Lin, Yue
Description: This study investigated the relationship of the Personnel Decisions International Employment Inventory scales to criminal behavior by using 796 offenders with criminal records in the Texas Department of Corrections and a random sample of 893 non-offender job applicants. The hypothesis that offenders would score lower in integrity scores than non-offenders only gained mixed support, but consistent evidence showed that there were no mean differences between property offenders and other offenders. The implications of the results for future study were discussed.

Investigating the hypothesized factor structure of the Noel-Levitz Student Satisfaction Inventory: A study of the student satisfaction construct.

Investigating the hypothesized factor structure of the Noel-Levitz Student Satisfaction Inventory: A study of the student satisfaction construct.

Date: December 2008
Creator: Odom, Leslie R.
Description: College student satisfaction is a concept that has become more prevalent in higher education research journals. Little attention has been given to the psychometric properties of previous instrumentation, and few studies have investigated the structure of current satisfaction instrumentation. This dissertation: (a) investigated the tenability of the theoretical dimensional structure of the Noel-Levitz Student Satisfaction Inventory™ (SSI), (b) investigated an alternative factor structure using explanatory factor analyses (EFA), and (c) used multiple-group CFA procedures to determine whether an alternative SSI factor structure would be invariant for three demographic variables: gender (men/women), race/ethnicity (Caucasian/Other), and undergraduate classification level (lower level/upper level). For this study, there was little evidence for the multidimensional structure of the SSI. A single factor, termed General Satisfaction with College, was the lone unidimensional construct that emerged from the iterative CFA and EFA procedures. A revised 20-item model was developed, and a series of multigroup CFAs were used to detect measurement invariance for three variables: student gender, race/ethnicity, and class level. No measurement invariance was noted for the revised 20-item model. Results for the invariance tests indicated equivalence across the comparison groups for (a) the number of factors, (b) the pattern of indicator-factor loadings, (c) the factor loadings, ...

An Exploration of the Criterion and Construct Validity of the Self-compassion Scale

An Exploration of the Criterion and Construct Validity of the Self-compassion Scale

Date: August 2014
Creator: Farnsworth, Jacob K.
Description: Past research indicates that self-compassion has positive implications for psychological health and functioning. However, as a newly specified construct, the literature regarding self-compassion could benefit from a more thorough validation of the primary scale used in this area of research, the Self-Compassion Scale. In the present study, structural path analysis (using Amos) was used to explore the criterion validity of the SCS with four variables which have been theorized to be relevant to self-compassion (caregiver emotional responsiveness, fear of emotion, internalized spirituality, and achievement goal orientation). Initial hypothesis testing indicated support for the path model, with the exception of achievement goals which were not significantly associated with self-compassion. Trimming these paths in a subsequent analysis improved model fit. Interestingly, further analyses of the model indicated that the pairing of participant and parent gender produced substantial differences in path coefficients. Next, correlational and factor analytic methods were used to test the construct validity of the SCS. Correlational analyses found adequate convergent construct validity but some lack of divergent validity between SCS dimensions and conceptually similar constructs (i.e., fear of emotion, social connectedness and self-criticism). Confirmatory factor analysis indicated that a two-factor model fit the data better than the one-factor model proposed ...
