Abstract Introduction The Sleep Inertia Questionnaire (SIQ) was developed and validated in patients with mood disorders to evaluate difficulties with becoming fully awake after nighttime sleep or daytime naps in a multidimensional manner. However, few data are available regarding its psychometric properties in clinical samples with sleep disorders. Methods 211 patients (43.0±16.4 years old, 68% female, 17% minority) evaluated at the Behavioral Sleep Medicine (BSM) program of Penn State Health Sleep Research & Treatment Center completed the SIQ. All patients were diagnosed using ICSD-3 criteria, with 111 receiving a diagnosis of chronic insomnia disorder (CID), 48 of a central disorder of hypersomnolence (CDH), and 52 of other sleep disorders (OSD). Structural equation modelling was used to conduct confirmatory factor analysis (CFA) of the SIQ. Results CFA supported four SIQ dimensions of “physiological”, “cognitive”, “emotional” and “response to” (RSI) sleep inertia with adequate goodness-of-fit (TLI=0.90, CFI=0.91, GFI=0.85, RMSEA=0.08). Internal consistency was high (α=0.94), including that of its dimensions (physiological α=0.89, cognitive α=0.94, emotional α=0.67, RSI α=0.78). Dimension inter-correlations were moderate to high (r=0.42–0.93, p<0.01), indicating good construct validity. Convergent validity showed moderate correlations with Epworth sleepiness scale (ESS) scores (r=0.38) and large correlations with Flinders fatigue scale (FFS) scores (r=0.65). Criterion validity showed significantly (p<0.01) higher scores in subjects with CDH (69.0±16.6) as compared to those with CID (54.4±18.3) or OSD (58.5±20.0). A SIQ cut-off score ≥57.5 provided a sensitivity/specificity of 0.77/0.65, while a cut-off score ≥61.5 provided a sensitivity/specificity of 0.71/0.70 to identify CDH vs. ESS<10 (AUC=0.76). Conclusion The SIQ shows satisfactory indices of reliability and construct validity in a clinically-diverse sleep disorders sample. Its criterion validity is supported by its divergent association with hypersomnia vs. insomnia disorders, as well as its adequate sensitivity/specificity to identify patients with CDH. The SIQ can help clinicians easily assess the complex dimensionality of sleep inertia and target behavioral sleep treatments. Future studies should confirm the best SIQ cut-off score by including good sleeping controls, while clinical studies should determine its minimal clinically important difference after pharmacological or behavioral treatments.

The purpose of this study was to examine the construct validity (internal structure) of the Kaufman Assessment Battery for Children (K-ABC) for use with Cantonese, English, and Punjabi speaking Canadians. A confirmatory factor analysis revealed that the sequential/simultaneous theoretical model was supported by the English and Punjabi data: however, the Cantonese data did not exhibit a good fit with this model. Similarly, the results of the exploratory factor analysis suggested that sequential and simultaneous factors could apply when describing the factor structure of the English and Punjabi data, but not for the Cantonese data. Implications of these findings are discussed.

This study aims to adapt the Sanctification of Marriage Questionnaire for Muslims inIndonesia. Adaptation of the Sanctification of Marriage Questionnaire is carried out throughthe stages: translation, providing evidence of construct validity and reliability. Evidence of construct validity was carried out by exploratory factor analysis followed by MGCFA (Multi-Group Confirmatory factor Analysis). In this study, we used a composite reliability. Subjects to reveal the factor structure of sanctification of marriage were 160 married individuals, while the subjects to test the stability of factor structure consisted of 102 husbands and 111 wives. The result of exploratory factor analysis shows that the construct of sanctification of marriage has three factors / dimensions, namely: belief, perceived sacred qualities and manifestation of God. The structure stability of sanctification of marriage was then empirically tested by MGCFA. The results of MGCFA showed that the three factors / dimensions of sanctification of marriage proved stable. The composite reliability coefficient of the Sanctification of Marriage Questionnaire was in a good category. Further research can be carried out to provide evidence of construct validity with predictive validity and concurrent validity of the Sanctification of Marriage Questionnaire. Limitations in this study are discussed further.Keywords: exploratory factor analysis, multi-group confirmatory factor analysis, muslim,sanctification of marriage, scale adaptation

AbstractThe following study is aimed at investigating the construct validity of the 25-item Connor-Davidson Resilience Scale (CD-RISC 25) on a Romanian military population. The exploratory factor analysis was conducted on 434 male military participants, aged between 24 and 50 years (M = 34.83, S.D. = 6.14) and the confirmatory factor analysis was conducted on a sample of 679 military participants, of 605 men and 74 women, aged between 18 and 59 years (M = 38.37, S.D. = 9.07). Factor analysis of the scale showed it to be a bidimensional, rather than a multidimensional instrument, as the original five-factor structure was not replicated in this military Romanian sample. Moreover, EFAs suggested that a 14-item bidimensional model should be retained and CFA confirmed that this model fit the data best.

Experience has different impacts for each individual. Individuals have several choices in the emotions one feels by regulating emotions. Emotion and emotional regulation take shape in a social context. This makes researchers interested in seeing messages, emotions in a social context. This formation is by looking at the results of the test results of the construct validity of the Indonesian version of the Interpersonal Emotion Regulation Questionnaire (IERQ) measuring instrument which has the same construct as the IERQ measuring instrument from Hofmann, Carpenter and Curtis (2016). It is hoped that this can contribute to measuring emotions that come from the social context in Indonesian. This research was conducted in May 2020 on 202 participants with adolescents aged 12-21 years. The factor analysis method used in this study is Confirmatory Factor Analysis (CFA) using the Lisrel program. The results of data analysis show that the construct validity of the IERQ measuring instrument which has been entered into Indonesian shows a positive and significant loading factor. This shows the Indonesian version of the IERQ construct with the same construct as the IERQ measuring instrument from Hofmann, Carpenter and Curtis. The results showed that the Indonesian version of the IERQ measuring instrument can be used by researchers to measure emotional regulation in adolescents in Indonesia. The next research can look in more detail and in-depth about the causes of people to do emotional regulation, and can try out the Indonesian version of the IERQ measurement tool on different participants. Pengalaman emosional merupakan suatu pengalaman yang pasti akan dialami oleh semua individu. Pengalaman emosional memberikan dampak yang berbeda-beda untuk setiap individunya. Individu memiliki beberapa pilihan dalam memodifikasi emosi yang dirasakan salah satunya dengan meregulasi emosi. Emosi dan regulasi emosi terbentuk dalam konteks sosial. Hal tersebut membuat peneliti tertarik untuk mengetahui pembentukan regulasi emosi dalam konteks sosial. Pembentukan tersebut dengan melihat hasil uji validitas konstruk alat ukur Interpersonal Emotion Regulation Questionnaire (IERQ) versi Indonesia memiliki konstruk yang sama dengan alat ukur IERQ dari Hofmann, Carpenter dan Curtis (2016). Hal tersebut diharapkan dapat memberikan sumbangan alat ukur regulasi emosi yang berasal dari konteks sosial dalam Bahasa Indonesia. Penelitian ini dilakukan pada bulan Mei 2020 terhadap 202 partisipan dengan karakteristik remaja berusia 12-21 tahun. Metode analisis faktor yang digunakan dalam penelitian ini adalah Confirmatory Factor Analysis (CFA) dengan menggunakan program Lisrel. Hasil analisis data menunjukkan validitas konstruk pada alat ukur IERQ yang sudah diterjemahkan kedalam Bahasa Indonesia menunjukan loading factor positif dan signifikan. Hal ini menunjukkan konstruk IERQ versi Bahasa Indonesia memiliki konstruk yang sama dengan alat ukur IERQ dari Hofmann, Carpenter dan Curtis. Hasil penelitian ini menunjukan bahwa alat ukur IERQ versi Bahasa Indonesia dapat dipergunakan oleh para peneliti untuk mengukur regulasi emosi pada remaja di Indonesia. Penelitian berikutnya dapat mengamati lebih mendetail dan mendalam mengenai penyebab orang-orang melakukan regulasi emosi, serta dapat mengujicobakan alat ukur IERQ versi Indonesia pada partisipan yang berbeda.

One distinguishing factor of individuals is their lifestyles. In the internet, every individual shows a different behavior while some groups have rather similar behaviors. By identifying these groups and their interests and preferences, it becomes possible to offer a product or advertising which is compatible with their wants. This leads to conveying the value presented by the producer to the consumer with high effectiveness. One source of identifying target customers or internet users is their lifestyle in internet space. The present study aims at describing and explaining internet lifestyle (e-lifestyle) of Iranian users. In particular, this study tries to find out the most common e-lifestyle of Iranian users. To this aim, 412 students involved with internet were surveyed. After estimating the construct validity of the study through confirmatory factor analysis, the mean scores of each e-lifestyle were compared by student t-test. The results revealed that Iranian users have mostly entertainment-driven e-lifestyles. The perceived importance-driven, sociability-driven, interest-driven, novelty-driven, need-driven, and uninterested or concern-driven e-lifestyles were respectively identified after that. This is the first study investigating the most common e-lifestyle among Internet users.

Introduction: We aimed to evaluate the psychometric properties of the 26-item Expanded Prostate Cancer Index Composite (EPIC-26) for measuring the quality of life in patients treated for localized prostate cancer. The EPIC-26 is a patient-reported outcome instrument recommended for use with patients treated for localized prostate cancer. Methods: This study is based on data collected prospectively between September 2014 and February 2017 in Alberta, Canada. Men were treated with either radical prostatectomy or radiation therapy and administered the EPIC-26. Responses to the EPIC-26 were the primary outcome. Construct validity was measured using confirmatory factor analysis. Reliability was measured using Chronbach’s alpha and item-total correlation. Ceiling and floor effects were also investigated. Results: EPIC-26 response data from 205 participants (prostatectomy =138; radiation=60; both=7) were used in this analysis. The EPIC-26 was administered an average of 33.8 weeks after treatment. The confirmatory factor analysis model did not meet the threshold for adequate fit. Several items had near-zero factor loadings and were non-significant. Four out of the EPIC- 26’s five domains met the acceptable reliability threshold based on Cronbach’s alpha. Ceiling effects were observed in four out of five domains. Conclusions: The EPIC-26 demonstrated poor construct validity, adequate reliability, and large ceiling effects. Several issues were observed, suggesting that the instrument’s five domains were not well-defined by their respective items. The original EPIC’s conceptual framework should be reviewed and the shortened instrument revised to improve its performance for measuring post-treatment quality of life.

Patient Enablement

Background: The purpose of our study was to develop and psychometrically test a German-language survey instrument that measures patient enablement generically and in greater detail than previous instruments. Methods: A multidisciplinary team developed 13 items to capture individual aspects of patient enablement (PEN-13). A pre-test with 26 subjects was followed by a random sample survey of N = 1168 subjects. An exploratory factor analysis was conducted in a random split-half sample of the data to explore PEN-13’s factor structure; a confirmatory factor analysis was conducted in the validation sample. The internal consistency of the factors was evaluated using Cronbach’s alpha, PEN-13’s construct validity was checked by means of additional hypothesis testing. Results: The two factors self-management and patient-practitioner interaction, detected in the exploratory analysis, were confirmed with a few modifications in the confirmatory factor analysis, with the comparative fit index (CFI) amounting to 0.903. The Cronbach’s alpha values of those two factors amounted to α = 0.90 and α = 0.82, respectively. The correlations of the PEN-13 score with the ’general self-efficacy’ and ’health literacy’ (HLS-EU-Q16) scores further confirmed its construct validity; the respective correlation coefficients amounted to 0.57 and 0.60. Conclusion: The German version of the survey instrument Patient Enablement Scale—13 items (PEN-13) shows acceptable psychometric properties. Practical implications: PEN-13 seems particularly suitable for health services research purposes. We recommend checking the results in another sample as well as evaluating its responsiveness to enablement-enhancing interventions.

This article reports initial evidence of construct validity for a four-factor measure of attributions assessing the dimensions of controllability, stability, globality, and universality (the CSGU). In Study 1, using confirmatory factor analysis, factors were confirmed across least successful and most successful conditions. In Study 2, following less successful performances, correlations supported hypothesized relationships between subscales of the CSGU and subscales of the CDSII (McAuley, Duncan, & Russell, 1992). In Study 3, following less successful performances, moderated hierarchical regression analyses demonstrated that individuals have higher subsequent self-efficacy when they perceive causes of performance as controllable, and/or specific, and/or universal. An interaction for controllability and stability demonstrated that if causes are perceived as likely to recur, it is important to perceive that causes are controllable. Researchers are encouraged to use the CSGU to examine main and interactive effects of controllability and generalizability attributions upon outcomes such as self-efficacy, emotions, and performance.
