This study provides preliminary evidence for the validity of the Bahasa Indonesian version of the Study Process Questionnaire (BI-SPQ) from a sample of 147 psychology students (22 men and 125 women; M age = 21.8 yr., SD=1.3). The internal consistency alpha of the BI-SPQ subscales were found to range from .46 (Surface Strategy) to .77 (Deep Strategy), with a median of .67. Principal component analysis indicated a two-factor solution, where the Deep and Achieving subscales loaded onto Factor 1 and the Surface subscales loaded on Factor 2. Students' GPAs were associated negatively with Surface Motive ( r = −.24) and were associated positively with Deep and Achieving Motives ( rs = .20). Further studies with larger samples involving students majoring in other disciplines are needed to provide further evidence of the validity of the BI-SPQ.

The aim of this study was to examine the relations among self-talk, self-consciousness, and self-knowledge through an exploratory principal component analysis and to test the hypothesis that only the functional and reflective aspects of self-consciousness contribute to self-knowledge. A self-report questionnaire including 6 scales assessing different aspects of self-talk, self-consciousness, and self-knowledge was administered to 203 German undergraduate university students. A principal component analysis of the scales yielded a two-factor solution, supporting the distinction between functional and dysfunctional self-consciousness. In a stepwise multiple regression analysis, only functional self-consciousness was a significant predictor of self-knowledge. Limitations of the present measures of inner speech are addressed.

Purpose: The purpose of this study is to report the initial validation process for using the Dermatology Life Quality Index (DLQI) for radiodermatitis of the breast. Methods: This is an additional analysis of a study designed to report a longitudinal study in skin-related and global quality of life in women with breast radiodermatitis. A total of 40 participants completed the DLQI instrument weekly while receiving external radiotherapy of the female breast. At week 5 on treatment, 31 (78%) participants provided narrative feedback on how each DLQI item affected her life. Agreement between participant DLQI numerical ratings and narrative feedback on items was assessed. Construct validity was estimated using principal component analysis (PCA). Internal consistency of the DLQI was assessed using Cronbach alpha. Results: Percentage of agreement between participant DLQI ratings and narratives ranged from 71% to 98%. Each participant responded “no” to the work and study item leading to zero variance and removal from our analyses. Principal component analysis supported the inclusion of all of the remaining items. The DLQI with nine remaining items demonstrated moderately good internal consistency (α = .69). Conclusions: The results of our examination of the DLQI when used for breast radiodermatitis are promising. Next steps include additional larger studies among more diverse populations.

The current study was conducted to examine the internal structure of the 1983 Participation Motivation Questionnaire of Gill, Gross, and Huddleston, a measure of motives for participating in sport and physical activity, when used among undergraduates. Principal component analysis of responses from students yielded a six-factor solution. The subscales were team orientation, achievement/status, fitness, friendship, skill development, and fun/excitement/challenge. The internal consistency for the subscales was generally adequate (coefficients alpha ranged from .67 to .93). Descriptive statistics indicated that the students' most important motives for participating in physical activity were to (a) maintain fitness, (b) experience fun, excitement, and challenge, and (c) acquire and improve skills. The least important motives for participating in physical activity were to (a) maintain and develop friendship, (b) obtain achievement and status, and (c) experience teamwork, team spirit, and being on a team. Avenues of research are discussed.

Introduction: The aim of this study is to explore the validation of the Resilience Scale in its long and brief versions (25 items and 14 items). This instrument assesses the individual’s ability to withstand stressors, thrive and make sense of vital challenges.Material and Methods: The sample included 511 Portuguese physicians. Both versions were validated through the study of internal structure validity, reliability, and convergent validity. The validity of the internal structure was analysed using the principal component analysis technique. Reliability was verified by the internal consistency study. For convergent validity, the correlation coefficients between these versions of the Resilience Scale and other scales validated to measure depression, anxiety, stress, and life satisfaction were calculated.Results: Both versions of Resilience Scale showed good internal consistency. For each of the versions, one factor was retained in the principal component analysis. Convergent validity was verified by significant positive correlations between Resilience Scale (25 and 14) and a life satisfaction scale and significant negative correlations between Resilience Scale and depression, anxiety, and stress subscales.Discussion: The results show the one-dimensional character of both versions of the Resilience Scale and support their usefulness and validity in the physician’s class. Conclusion: This is the first validation study of this scale in a group of physicians. Its results are very satisfactory, and its use in this specific group is recommended.

This study investigated the emergence of different factors in the framing of Panama leaks by gathering data along with five thematic frames of financial, morality, blame-game, political victimization, and accountability. Altogether 930 news stories were content analyzed to investigate how the issue of Panama leaks was framed in the media since its inception in April 2016. Furthermore, 22 framing items were selected to measure these frames and a principal component analysis resulted in generating a factor solution by clustering of these framing items into eight distinguishable factors of political-econo, governance, justificationssolutions, socio-political responsibility, implications, apathy, responsiveness, and economic instability. This study revealed differences in the use of these factors both in different newspapers and topics of coverage. The Pakistani press used the factor of governance more whereas the western press used the factor of political-econo more as compared to other factors in the framing of Panama leaks.

Abstract Background The study aimed to translate the foot function index (FFI) questionnaire to Thai and to determine psychometric properties of the questionnaire among individuals with plantar foot complaints. Methods The Thai version of the FFI (FFI-Th) was adapted according to a forward and backward translation protocol by two independent translators and analyzed by a linguist and a committee. The FFI-Th was administered among 49 individuals with plantar foot complaints to determine internal consistency, reliability, and validity. Cronbach’s alpha and the Intraclass Correlation Coefficient (ICC3,1) were used to test the internal consistency and test-retest reliability. The Principal Component Analysis with varimax rotation method was used to test the factor structure and construct validity. Furthermore, the criterion validity was tested using Pearson’s correlation coefficient (rp) between the FFI-Th and the visual analogue pain scale (pain-VAS) as well as the EuroQol five-dimensional questionnaire (EQ-5D-5L). Results The FFI-Th showed good to excellent internal consistency and test-retest reliability in the total score, pain, disability, and activity limitation subscales. The Principal Component Analysis produced 4 principal factors from the FFI-Th items. Criterion validity of the FFI-Th total score showed moderate to strong correlations with pain-VAS and EQ-5D-5L, and EQ-VAS scores. Conclusion The FFI-Th was a reliable and valid questionnaire to assess the foot function in a Thai population. Trial registration NCT03161314 (08/05/2017).

Generator Output

During conceptual design it is desirable to produce many potential solutions. Recently, computational tools have emerged to help designers more fully explore possible solutions. These automated concept generators use knowledge from existing products and the desired functionality of the new design to suggest solutions. While research has shown these tools can increase the variety of solutions developed, they often provide unmanageably large sets of poorly differentiated results. This work proceeds from the hypothesis that automated concept generator output includes many permutations of a relatively few principal solution variants. A method to discover these underlying solution types from the initial concept generator output is proposed. The proposed method employs principal component analysis for variable reduction followed by cluster analysis for classification. The method is applied to the automatically generated solutions of three sample design problems. Preliminary evidence of the utility and efficiency of the proposed method is presented based upon those sample problems. Finally, a method for extending the proposed technique to much larger solution sets is discussed.

IntroductionThe FMPS is a 35-item self-report questionnaire to measure perfectionism. It evaluates: concern over mistakes/CM, doubts about actions/DA, parental criticism/PC and expectations/PE, personal standards/PS and organization/O.ObjectivesTo develop a shortened version of FMPS and study its internal consistency, the construct, concurrent and divergent validity.MethodsOne hundred and ninety-two university students (78.1% females), aged 19.74 years (sd = 2.10) completed the Portuguese versions of the: FMPS, Hewitt and Flett MPS/H&FMPS, Life Orientation Test Revised/LOT-R, State-Trait Anxiety Inventory/STAI, and Profile of Mood States/POMS.ResultsCorrelations between each item and corrected FMPS total scores/corrected total subscales scores were ≥ 0.20 for the items 13, 15, 25, 31, 35 and 10, 2, 25, and 26, respectively. The internal consistency of FMPS was high (α: .857) with 32 items contributing for this consistency (exceptions: 13, 25 and 31). The principal component analysis of the 35 items with factors varimax rotation was performed. The three items with higher loading in each factor that also contributed to the FMPS reliability were selected for the FMPS shortened version (FMPS-18). The principal component analysis of the 18 items with factors varimax rotation showed that six factors explained 74.6% of FMPS-18 total variance. These factors revealed adequate internal consistency (α: O = 0.740; PC = 0.859; PE = 0.847; PS = 0.726; CM = 0.740; DA = 0.832; total = 0.768). Convergent correlations between FMPS and the matched FMPS-18 scores were 0.839 to 0.971 (all P < .01). Correlations of the FMPS-18 and FMPS with H&F-MPS, STAI, LOT-R and NA/PA scores were of similar significance and valence.ConclusionFMPS-18 is a brief, reliable and valid instrument to measure perfectionism.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Decisional Procrastination

The present study explored the factorial structure of three well-known procrastination measures: the General Procrastination Scale (GP; Lay, 1986 ), the Adult Inventory of Procrastination (AIP; McCown & Johnson, 1989 ), and the Decisional Procrastination Scale (DP; Mann, 1982 ) with 502 Spanish adults between 25 and 67 years old. The principal component analysis indicated a one-factor structure for GP and DP, and two factor components for AIP. The internal consistency of the three scales was satisfactory. Results suggested that the Spanish versions of the three procrastination scales were effective and reliable. Finally, a principal component analysis with the three scales indicated a four-factor model of procrastination, namely: dilatory behaviors, indecision, lack of punctuality, and lack of planning.
