The Job Insecurity Scale: A psychometric evaluation across five European countries

Multiple instruments have been developed and used to measure quantitative job insecurity (i.e., insecurity to lose the job as such), often without systematic evaluation of their psychometric characteristics across countries and language barriers. This may hamper consistent and reliable cross-study and cross-country comparisons. This study's aim was to introduce and validate the four-item Job Insecurity Scale (JIS) developed by De Witte across five European countries (i.e., Belgium, The Netherlands, Spain, Sweden, and the UK). Overall, the results demonstrated the construct validity (i.e., configural invariance and invariance of the measurement model parameters), the reliability (internal consistency of the items), and the criterion validity (with respect to affective organizational commitment, perceived general health, and self-reported performance) of the JIS. The different translations of the JIS can thus be considered as valid and reliable instruments to measure job insecurity and can be used to make meaningful comparisons across countries. Furthermore, the JIS translations may be utilized to assess how job insecurity is related to outcomes.     

Response inhibition and avoidance of virtual obstacles during gait in healthy young and older adults

Adjustments of preplanned steps are essential for fall avoidance and require response inhibition. Still, inhibition is rarely tested under conditions resembling daily living. We evaluated the ability of young and older adults to modify ongoing walking movements using a novel precision step inhibition (PSI) task combined with an auditory Stroop task.Healthy young (YA, n = 12) and older (OA, n = 12) adults performed the PSI task at 4 individualized difficulty levels, as a single and dual task (DT). Subjects walked on a treadmill by stepping on virtual stepping stones, unless these changed color during approach, forcing the subjects to avoid them. OA made more failures (40%) on the PSI task than YA (16%), but DT did not affect their performance. In combination with increased rates of omitted Stroop task responses, this indicates a “posture first” strategy. Yet, adding obstacles to the PSI task significantly deteriorated Stroop performance in both groups (the average Stroop composite score decreased by 13% in YA and 27% in OA). Largest deficit of OA was observed in rates of incorrect responses to incongruent Stroop stimuli (OA 35% and YA 12%), which require response inhibition. We concluded that the performance of OA suffered specifically when response inhibition was required.     

Self-reported problems: a comparison between PTSD-diagnosed veterans,their spouses,and clinicians

This study investigated self-reported problems in a sample of help-seeking Vietnam veterans, comparing the veteran's own view with clinician and spouse perspectives, with the aim of examining convergence in reports across different informants. Veterans with PTSD (N = 459) were asked to list and rate their five most serious problems. Spouses and treating clinicians completed the same questionnaire in relation to the veteran. Rates of endorsement for each problem area, and levels of agreement between raters, were calculated. Veterans, spouses, and clinicians were all likely to rate anger as a high priority, with veterans also likely to nominate anxiety and depression. Spouses were likely to nominate more observable behavioural problems such as interpersonal difficulties and avoidance, while clinicians were likely to nominate indications of psychopathology, such as anxiety, depression, and intrusive thoughts. Agreement across raters was generally high, although interpretation of agreement levels was complex.     

Characteristics of older cyclists (65+) and factors associated with self-reported cycling accidents in the Netherlands

Cycling supports the mobility, health and independency of the ageing population. However, older cyclists have an increased injury risk. On average, the risk of older people to sustain an injury in a cycling accident is three times higher per cycling kilometre than for middle-aged people and the injury risk increases with age. In comparison with middle-aged cyclists (<65 years), the risk of hospitalization is more than four times as high for older cyclists (≥65 years). The aim of this study was to reveal characteristics of older cyclists in general and to explore which of these characteristics are associated with self-reported cycling accidents from age 59. More than eight hundred older cyclists (>65 years) filled out a questionnaire, which included questions on demographics, bicycle specifications and personal characteristics. By means of a logistic regression, the relationship between personal factors and self-reported bicycle falls were studied. The univariate models showed that age, physical and mental impairments, bicycle model, living environment, feelings of uncertainty of the cyclist and changed cycling behaviour (such as more patience, lower speed) were related to falling off a bicycle. From the multivariate model we can conclude that several factors are associated with falling off a bicycle in the older population: (1) every year the cyclists becomes one year older (from the age of 65), the chance they have fallen increases with 7.3%, (2) If cyclists have mental impairments, the chance they have fallen increases with a factor 2.5, (3) if cyclists were less than completely confident the chance they have fallen increases with factor 1.8, (4) if cyclists live in a rural environment compared to an urban environment the chance they have fallen increases with a factor 2.1. In conclusion, demographic, cycling and personal factors can be related to increased self-reported fall risk. It is advised to take these factors into account when implementing new cycling related safety measures.     

Further Evidence of the Reliability and Validity of the Multidimensional Anxiety

The psychometric properties of the Multidimensional Anxiety Scale for Children (MASC) were examined in adolescent psychiatric inpatient samples. In Study 1 (n = 287), confirmatory factor analyses provided satisfactory fit for the four-factor (comparative fit index; CFI = 0.856) and higher-order (CFI = 0.854) solutions. Using parcels as items, the fit of the four-factor model was improved substantially (CFI = 0.935). Next, in the bifactor analyses, support was attained for a model that included a general factor and four domain specific subfactors. In Study 2 (n = 195 inpatient youths), the MASC showed good scale reliability and concurrent validity. Results of the receiver operating characteristic curve and binary logistic regression analyses provided adequate evidence for discriminative validity. In Study 3 (n = 40), test–retest reliability of scores on the MASC-10 scale over a 3-week period was adequate (r _tt = 0.83, p < 0.001) for children ages 8 to 11 years.     

Development and preliminary validation of the Penny Beliefs Scale – Weapons (PBS-W)

Weapons carrying and use is an area of increasing concern and frequent media attention. Despite this, there is a distinct lack of psychological research into the reasons that people carry and use weapons. At present there is no adequate measure of beliefs that facilitate carrying and using weapons and the present investigation sought to develop and validate such a tool: the Penny Beliefs Scale - Weapons (PBS-W). The PBS-W was developed using themes identified in a literature review and through consultation with experienced Forensic Psychologists. The factor structure, reliability, and validity were ascertained by administering the PBS-W to 212 school pupils in South Wales, who were aged between 16 and 18 years. The final version of the PBS-W comprises of 36 items that measure young people’s beliefs about carrying and using weapons and load onto one factor named Potency. The new scale has excellent internal reliability (Cronbach’s alpha of .92), extremely good test-retest consistency (ICC = .833), male participants scored significantly higher on the PBS-W compared with female participants, and the PBS-W is significantly positively correlated with self-reported delinquency. These findings are discussed in the context of existing literature and future potential directions for research are proposed.     

Predicting incident falls: Relationship between postural sway and limits of stability in older adults

BackgroundWe have previously shown that objective measurements of postural sway predicts fall risk, although it is currently unknown how limits of stability (LOS) might influence these results.Research question: How integrated postural sway and LOS measurements predict the risk of incident falls in a population-based sample of older adults.Methods:The sample for this prospective observational study was drawn from the Healthy Ageing Initiative cohort and included data collected between June 2012 and December 2016 for 2396 men and women, all 70 years of age. LOS was compared to postural sway with measurements during eyes-open (EO) and eyes-closed (EC) trials, using the previously validated Wii Force Plate. Fall history was assessed during baseline examination and incident falls were collected during follow-up at 6 and 12 months. Independent predictors of incident falls and additional covariates were investigated using multiple logistic regression models.Results:During follow-up, 337 out of 2396 participants (14%) had experienced a fall. Unadjusted regression models from the EO trial revealed increased fall risk by 6% (OR 1.06, 95% CI 1.02–1.11) per each centimeter squared increase in sway area and by 16% (OR 1.16, 95% CI 1.07–1.25) per 1-unit increase in Sway-Area-to-LOS ratio. Odds ratios were generally lower when analyzing EC trials and only slightly attenuated in fully adjusted models.Significance:Integrating postural sway and LOS parameters provides valid fall risk prediction and a holistic analysis of postural stability. Future work should establish normative values and evaluate clinical utility of these measures.     

Exploring the relationship between the Five-Factor Model of personality,social factors and self-reported delinquency

The ‘Big Five’ is one of the predominant models of personality structure but relatively little research has focussed on how the five factors might be related to self reported offending separately for males and females. This is problematic for understanding the relationship between personality and offending as females and males typically have different personality profiles and differ considerably in self-reported offending. In this research 720 adolescents (376 males and 344 females) completed a Big Five personality measure along with measures of self-reported offending, socioeconomic status and family structure. The results suggested that low agreeableness and low conscientiousness were independently related to the prevalence of self-reported offending for males and that low agreeableness was independently related to frequent male offending. Low conscientiousness was independently related to female offending, but so too were interactions between disrupted family and extraversion and disrupted family and openness. The interaction between extraversion and a disrupted family was also independently related to frequent female offending. Limitations and directions for future research are discussed.     

Teachers' conflict management styles: The role of attachment styles and classroom management efficacy

Constructive conflict management strategies are important in maintaining a positive classroom environment yet little is known about interpersonal or school variables associated with teachers' use of such strategies with students. Teachers high in self-reported classroom management efficacy (CMEFF) and security of attachment (low on avoidance, anxiety) were predicted to endorse use of positive classroom management strategies (e.g., integrating, compromising) more than insecure teachers and those low in CMEFF. Teachers (N = 283) from eleven schools (seven elementary), largely female and white, responded to a questionnaire in their boxes (29.4% response rate). School and teacher demographic variables were included in a multivariate regression after preliminary analysis suggested that ignoring the multilevel structure of the data made little difference in results; school variances were small compared with teacher variances. CMEFF and years teaching had positive, significant effects on use of integrating and compromising strategies, while avoidance had negative effects on both and anxiety on integrating strategies. Implications for teacher development are discussed.     

Do sport modes cause behavioral adaptation?

A key question in transportation research is whether drivers show behavioral adaptation, that is, slower or faster driving, when new technology is introduced into the vehicle. This study investigates behavioral adaptation in response to the sport mode, a technology that alters the vehicle’s auditory, throttle-mapping, power-steering, and chassis settings. Based on the literature, it can be hypothesized that the sport mode increases perceived sportiness and encourages faster driving. Oppositely, the sport mode may increase drivers’ perceived danger, homeostatically causing them to drive more slowly. These hypotheses were tested using an instrumented vehicle on a test track. Thirty-one drivers were asked to drive as they normally would with different sport mode settings: Baseline, Modified Throttle Mapping (MTM), Artificial Engine Sound enhancement (AESe), MTM and AESe combined (MTM-AESe), and MTM, AESe combined with four-wheel steering, increased damping, and decreased power steering (MTM-AESe-4WS). Post-trial questionnaires showed increased perceived sportiness but no differences in perceived danger for the three MTM conditions compared to Baseline. Furthermore, compared to Baseline, MTM led to higher vehicle accelerations and, with a smaller effect size, a higher time-percentage of driving above the 110 km/h speed limit, but not higher cornering speeds. The AESe condition did not significantly affect perceived sportiness, perceived danger, and driving speed compared to Baseline. These findings suggest that behavioral adaptation is a functional and opportunistic phenomenon rather than mediated by perceived sportiness or perceived danger.
