Effect of verbal cueing on trajectory anticipation in the penalty kick among novice football goalkeepers

The effect of a cueing technique on novice goalkeepers' anticipation of trajectory in penalty kicks was investigated. 28 novice football goalkeepers from junior teams were randomly selected and divided into experimental (n = 14) and control (n = 14) groups. Following a pre-test, participants performed 30 trials of a simulated penalty-kicking task in a spatially occluded condition. They were required to react to penalty kicks and were informed of their performance in anticipating the direction in which the ball was kicked. The experimental group received cues about the position of the non-kicking foot of the kicker, but the control group did not. The two-way analysis of variance showed the significant main effects of blocks of trials and group, but the interaction was not significant. The experimental group more accurately anticipated the direction of the penalty kicks than the control group. The cueing technique benefited the novice goalkeepers in anticipating the direction of penalty kicks, due to the informative nature of the cue for skill execution.     

Ground reaction force adaptations during cross-slope walking and running

Though transversely inclined (cross-sloped) surfaces are prevalent, our understanding of the biomechanical adaptations required for cross-slope locomotion is limited. The purpose of this study was to examine ground reaction forces (GRF) in cross-sloped and level walking and running. Nine young adult males walked and ran barefoot along an inclinable walkway in both level (0°) and cross-slope (10°) configurations. The magnitude and time of occurrence of selected features of the GRF were extracted from the force plate data. GRF data were collected in level walking and running (LW and LR), inclined walking and running up-slope (IWU and IRU), and down-slope (IWD and IRD), respectively. The GRF data were then analyzed using repeated measures MANOVA. In the anteroposterior direction, the timing of the peak force values differed across conditions during walking (p=.041), while the magnitude of forces were modified across conditions for running (p=.047). Most significant differences were observed in the mediolateral direction, where generally force values were up to 390% and 530% (p<.001) larger during the cross-slope conditions compared to level for walking and running, respectively. The maximum force peak during running occurred earlier at IRU compared to the other conditions (p≤.031). For the normal axis a significant difference was observed in the first maximum force peak during walking (p=.049). The findings of this study showed that compared to level surfaces, functional adaptations are required to maintain forward progression and dynamic stability in stance during cross-slope walking and running.     

The Complexity of the Relation between Fear of Failure and Procrastination

This study investigated the indirect and conditional relation between fear of failure and procrastination based on constructs from self-determination theory. Using structural equation modeling to analyze data from 300 university students, we found that the relation between fear of failure and procrastination was moderated by perceived competence. The relation was positively significant for students with low levels of competence and negatively significant for those with high level of competence. However, in the latter group, fear of failure negatively affected satisfaction of the need for autonomy, which in turn increased the likelihood of problematic delay on academic and everyday-life tasks. The results are discussed in relation to the complex interplay of motivational variables related to self-regulatory failure.     

Psychometric Properties of the Persian Spiritual Coping Strategies Scale in Hemodialysis Patients

Spiritual strategies may provide an effective way of coping with disease. This study sought to investigate the validity and reliability of the Persian version of the spiritual coping strategies (SCS) scale among Iranian hemodialysis patients. A convenience sample of 204 hemodialysis patients was recruited to participate in the study. A forward–backward translation method was used to produce the Persian version of the scale. Internal consistency was assessed by Cronbach’s alpha and item–total score correlation. Two-week test–retest reliability was also assessed. The convergent and divergent validity of the scale was evaluated using the Duke University Religion Index and a visual analogue scale for health status. Exploratory and confirmatory factor analyses were used to assess the factor structure. Participants consisted of 113 males and 91 females (mean age 57.2 [SD = 9.7]). Cronbach’s alpha was acceptable (0.87). We found two underlying factors similar to the original scale. The correlations between the study scales confirmed the convergent and divergent validity of the SCS. Confirmatory factor analysis showed a good fit to the data (GFI = 0.923, CFI = 0.948 and RMSEA = 0.068). The Persian version of the SCS has sound psychometric properties in Iranian hemodialysis patients. Future research should consider applying the scale to populations with other religious/cultural backgrounds.     

Gender Differences in the Effects of Community Violence on Mental Health Outcomes in a Sample of Low-Income Youth Receiving Psychiatric Care

Previous research suggests that community violence impacts mental health outcomes, but much of this research has not (a) distinguished between different types of community violence, (b) examined gender differences, and (c) focused on youth living in urban poverty. The current study addresses these questions. Participants were 306 youth (23 % girls) and one parent/guardian receiving outpatient psychiatric services for disruptive behavior disorders in a large urban city. Youth and parents reported on youth’s experience of different types of community violence (being a direct victim, hearing reports, and witnessing violence), and whether violence was directed toward a stranger or familiar. Outcomes included youth externalizing, internalizing, and posttraumatic stress symptoms assessed via parent and youth reports. Being a direct victim of violence accords risk for all mental health outcomes similarly for both boys and girls. However, gender differences emerged with respect to indirect violence, such that girls who hear reports of violence against people they know are at increased risk for all assessed mental health outcomes, and girls who witness violence against familiars are at increased risk for externalizing mental health symptoms in particular. There are gender differences in violence-related mental health etiology, with implications for intervention assessment and design.     

The influence of fear of happiness beliefs on responses to the satisfaction with life scale

General life satisfaction scales are widely used to examine the degree to which people are satisfied with their lives. Previous research indicates that part of the variability in life satisfaction scores does not genuinely reflect individuals’ life conditions, and that there are factors biasing people’s responses to these scales. The present study provided initial evidence showing that the fear of happiness (a belief that happiness may have negative consequences) influenced people’s responses to the items of a life satisfaction scale in an Iranian university student sample. Implications of the results are discussed.     

Measurement invariance of the Mental Health Continuum-Short Form (MHC-SF) across three cultural groups

This study investigated the factorial structure and invariance of the Mental Health Continuum-Short Form (MHC-SF) across cultural groups from three nations, namely, the Netherlands, South Africa, and Iran (N = 1120). The three-dimensional structure of mental well-being was supported in all the groups. The results of measurement invariance testing confirmed the full metric and partial scalar invariance of the MHC-SF. The study also compared the latent means for the aspects of mental well-being in the three cultural groups, and found significant differences. The significance and implications of the results are discussed.     

University Student Depression Inventory: Measurement model and psychometric properties

University Student Depression Inventory (USDI) was developed to assess the symptoms of depression among the university students. Considering the debilitating nature of depression among university students globally, USDI was translated in Persian and validated using university students from Iran. A battery including the Persian version of USDI and scales measuring suicide, depression, and stress was administered to a normative sample of 359 undergraduate students, and an additional clinical sample of 150 students referred to the university's mental health centre. The results supported the factor structure and the psychometric properties of the translated version. Confirmatory factor analysis upheld the previously reported three‐factor first‐order and one‐factor second‐order structure. The internal consistency, test‐retest reliability, and concurrent and discriminant validity of the Persian version were supported. Cut‐off points using receiver operating characteristic curve analysis were established to identify students at risk. Gender differences on the symptoms of depression were evident only in the normative sample, where male participants, compared with female students, had higher mean scores in lethargy, cognitive/emotion, and academic motivation subscales. The translated scale can be used with Persian‐speaking students in Iran and the neighbouring countries as well as those settled in the West to identify symptoms of depression for further evaluation and management.     

A Comparison of Western and Islamic Conceptions of Happiness

Research on the confluence of culture and mental health has grown dramatically in the past three decades. However, this line of research has focused almost entirely on western populations and largely neglected people from other regions. Western conceptualizations of positive functioning cannot be generalized to the Muslim populations before indigenous investigations are undertaken. This paper looks at the Muslim understanding of a good life. A brief review of the conceptualizations of happiness in the West is presented first. Next, a selection of Islamic teachings relevant to the concept of happiness is compared and contrasted with scholarship originating from the West. It is hoped that this theoretical analysis will stimulate more informed empirical research among Muslim psychologists.
