Aims of the study were to evaluate the reliability and validity of the Italian version of the Majeed and Iowa questionnaires and to investigate the long-term surgical outcomes following sacroiliac joint arthrodesis. Twenty one patients who underwent a sacroiliac joint arthrodesis and 21 healthy subjects were evaluated. The experimental procedure consisted of gait analysis and a physical activity assessment (in both groups) and of administration of outcome questionnaires and pain assessment (in the patient group). The Majeed and Iowa questionnaires showed excellent reliability, excellent (for the Majeed questionnaire) and good (for the Iowa questionnaire) construct validity, and poor convergent validity (for both questionnaires) relative to walking speed. Most of the patients reported no pain and minimum pain-related disability and their physical activity profile was comparable to healthy controls. Patients showed an impaired walking performance (i.e., they walked slower and using shorter steps) compared with healthy controls. Long-term walking pattern abnormalities following sacroiliac joint arthrodesis may occur despite excellent clinical results. Given their excellent reliability and construct validity, the Majeed and Iowa questionnaires can be used in combination with the assessment of spatiotemporal gait parameters for the prognostic assessment and/or follow-up of surgical patients.

This study presents the development and testing of the Overeating Tension Scale. Overeating tension was defined operationally as the total discrepancy score resulting from differences between subjects’ ratings of actual and desired feelings before overeating. The 32-item Overeating Tension Scale, derived from Apter’ s Reversal Theory, measures reported overall tension and motivation-specific tension. The scale initially included 48 items, six items for each of eight motivational states. After two instrument development studies (N = 373, N = 208), items were refined and reduced to a total of 32, or four for each of eight motivational states. The final version of the instrument was tested in two additional studies (N = 330, N = 130) that provided evidence to support the internal consistency reliability of the Overeating Tension Scale. There was support for construct validity using contrasted groups (overweight and normal weight subjects), convergent validity, and factor analysis.

Background:Psychosocial factors have been related to physical activity (PA) and are used to evaluate mediation in PA interventions.Methods:Brief theory-based psychosocial scales were compiled from existing measures and evaluated. Study 1 assessed factor structure and construct validity with self-reported PA and accelerometry in overweight/obese men (N = 441) and women (N = 401). Study 2 assessed 2-week reliability and internal consistency in 49 college students.Results:Confirmatory factor analysis indicated good fit in men and women (CFI = .90; RMSEA = .05). Construct validity was supported for change strategies (r = .29–.46), self-efficacy (r = .19–.22) and enjoyment (r = .21–.33) in men and women, and for cons in women (r = –.19 to –.20). PA pros (r = –.02 to .11) and social support (r = –.01 to .12) were not supported for construct validity. Test-retest reliability ICCs ranged from .49–.81. Internal consistency alphas ranged from .55–.90. Reliability was supported for most scales with further testing needed for cons (alphas = .55–.63) and enjoyment (ICC = 49).Conclusions:Many of the brief scales demonstrated adequate reliability and validity, while some need further development. The use of these scales could advance research and practice in the promotion of PA.

The Impact

Objective: The primary aims of the study were to examine the reliability and validity of the Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA) in a sample of adolescents requiring medium to long-term in-patient psychiatric treatment and to examine the association between HoNOSCA scores and age, gender and length of treatment. Methods: A multidisciplinary team completed the HoNOSCA for 51 adolescent patients at intake and at 3- and 6-months following admission to the unit. Results: The study provided support for the test-retest reliability, concurrent and convergent validity, but not the internal reliability, of the HoNOSCA. Total HoNOSCA scores at intake were similar to those found in adolescent outpatient samples, although there were some differences at the level of individual items. Similarly, while the total HoNOSCA score showed some sensitivity to change, using the total HoNOSCA score obscured important changes in specific domains of functioning over the course of admission. Conclusion: The HoNOSCA was found to be a valid measure of global functioning at intake, thereby supporting its use in an adolescent psychiatric unit. However, focusing on individual items, rather than total score, appears more useful in evaluating the impact of inpatient psychiatric treatment on adolescents.

OBJECTIVE: Assess the reliability and validity of the Exercise Benefits/Barriers Scale (EBBS) in the elderly. METHODS: The reliability was assessed by internal consistency (Cronbach's alpha) and by the test-retest Kendall's W. To verify the construct validity it was used a correlation between the EBBS results and the personal and clinic variables. RESULTS: The Cronbach's alfa of the EBBS was 0.94. The test-retest value was 0.60. The variables that presented association with the EBBS were: level of education (p = 0.02), practice of physical activity (p = 0.0001), with whom one resides (p= 0.032) and lifestyle (p= 0.0001). CONCLUSION: The statistical analysis revealed that the translated version of the EBBS is valid and reliable however, its use is recommended in different scenarios due to regional differences in Brazil, in order to have the validity of the instrument widely exploited.

Barriers To Physical Activity

Few studies have explored barriers to physical activity in parks and streets among children, adolescents, and their parents. The purpose of this article is to evaluate the psychometric properties of a new survey of barriers to physical activity in neighborhood parks and streets. Adolescents and parents of children and adolescents completed surveys twice. Two barrier subscales (environment and safety) emerged that applied to both locations and all participant groups. Results generally supported acceptable, internal consistency as well as construct validity, but test-retest reliabilities were lower than desired. These scales may be used to improve understanding of perceptions of barriers to physical activity in neighborhood parks and streets, but further development is needed.

Skills Transfer

Purpose:A signature characteristic of positive youth development (PYD) programs is the opportunity to develop life skills, such as social, behavioral, and moral competencies, that can be generalized to domains beyond the immediate activity. Although context-specific instruments are available to assess developmental outcomes, a measure of life skills transfer would enable evaluation of PYD programs in successfully teaching skills that youth report using in other domains. The purpose of our studies was to develop and validate a measure of perceived life skills transfer, based on data collected with The First Tee, a physical activity-based PYD program.Method:In 3 studies, we conducted a series of steps to provide content and construct validity and internal consistency reliability for the life skills transfer survey (LSTS), a measure of perceived life skills transfer.Results:Study 1 provided content validity for the LSTS that included 8 life skills and 50 items. Study 2 revealed construct validity (structural validity) through a confirmatory factor analysis and convergent validity by correlating scores on the LSTS with scores on an assessment tool that measures a related construct. Study 3 offered additional construct validity by reassessing youth 1 year later and showing that scores during both time periods were invariant in factor pattern, loadings, and variances and covariances. Studies 2 and 3 demonstrated internal consistency reliability of the LSTS.Conclusion:Results from 3 studies provide evidence of content and construct validity and internal consistency reliability for the LSTS, which can be used in evaluation research with youth development programs.

Objective: To evaluate the reliability and validity of a brief measure of successful aging in a sample of adults with long-term health conditions. Method: The brief (eight-item) version of the valued living scale (VLS) and measures of pain intensity, pain interference, and depression were administered to 1,457 adults aging with one of four long-term health conditions. Results: Analyses indicated that the VLS items assessed two types of valued living domains: (a) a social and relational domain and (b) a health and productivity domain. The findings also supported the construct validity for the VLS items, in that both domains were associated significantly (and negatively) with the measures of pain intensity, pain interference, and depression. Discussion: The results provide preliminary support for the reliability and validity of the VLS items for assessing two important domains of successful aging in individuals with long-term health conditions.

Momentary State

Stress is ubiquitous in everyday life and hazardous for mental and physical health. To prevent or ameliorate stress-related disease, approaches such as relaxation exercises aim to counteract stress by inducing short-lasting states of relaxation. Critically, current assessments capture the mid- and long-term consequences of relaxation but are unable to quantify these states of relaxation. To address this problem, we developed the Relaxation State Questionnaire (RSQ). We assessed the item properties, reliability, and validity of the questionnaire in an online study. Construct validity was examined through correlations with the Perceived Stress Questionnaire (PSQ; Fliege et al., 2005). An exploratory factor analysis revealed four factors capturing the momentary state of muscle tension, sleepiness, cardiovascular activity, and general relaxation. The items had high loadings on their factors and the reliability and construct validity of the RSQ were both high. These findings establish the RSQ as a tool to measure states of relaxation. As such, the RSQ opens up investigations of the immediate effects and effectiveness of relaxation exercises.

Abstract Objective: The current study evaluated the reliability and validity of the Arabic version of the revised general nutrition knowledge questionnaire (GNKQ-R) for adults. Design: The eighty-eight-item English GNKQ-R was adapted into an eighty-six-item Arabic version. Four validation studies were conducted for internal (n 805) and external (n 106) reliability, construct validity between participants with (n 84) and without (n 88) nutrition background, convergent validity for associations between nutrition knowledge and demographic characteristics (n 750) and responsiveness to online nutrition information (n 55). Setting: United Arab Emirates University in United Arab Emirates and Hashemite University in Jordan. Participants: Undergraduate students aged 18 years and above, enrolled in any programme at the two universities, were recruited. Results: Overall, internal reliability (Cronbach’s α = 0·91) and external reliability (P = 0·350; intra-class correlation coefficient = 0·84) were high. Significantly higher GNKQ-R scores of students with (66·0 (10·6)) v. without (38·0 (10·7), P < 0·001; d = 2·6) nutrition background indicated high construct validity. Significantly higher GNKQ-R scores among females v. males, older and senior students v. younger and junior students and students in health discipline v. non-health discipline reflected good convergent validity. Significant differences in GNKQ-R scores with nutrition information (time 1 = 37·8 (10·5) and time 2 = 47·7 (9·1), P < 0·001; d = 1·0) indicated high responsiveness to nutrition intervention. Conclusions: The Arabic GNKQ-R showed high reliability and validity in the young adult Arab population. Besides the reliability of the overall questionnaire, each section demonstrated adequate reliability. Further studies are warranted to establish the generalisability and applicability of the Arabic GNKQ-R in older adults and in different middle-eastern Arab countries.
