Social Anxiety Scale for Adolescents (SAS-A): Measuring Social Anxiety Among Finnish Adolescents

The aim of this study was to investigate symptoms of social anxiety and the psychometric properties of the Social Anxiety Scale for Adolescents (SAS-A) among Finnish adolescents, 13–16 years of age. Study 1 (n = 867) examined the distribution of SAS-A scores according to gender and age, and the internal consistency and factor structure of the SAS-A. In a subsample (n = 563; Study 2) concurrent and discriminant validity of the SAS-A were examined relative to the Social Phobia Inventory and the Beck Depression Inventory. Test–retest stability was examined over a 30-month period by repeated measures every 6 months in another subsample (n = 377; Study 3). Results mostly revealed no gender differences in social anxiety, except that boys reported more general social avoidance and distress than girls. Older adolescents (14–16-year-olds) reported higher social anxiety than younger adolescents (12–13-year-olds). Internal consistency for the SAS-A was acceptable for both genders and for all three SAS-A subscales. Confirmatory factor analysis replicated the original 18-item three-factor structure of the SAS-A, accounting for 61% of the variance between items. Evidence for concurrent and discriminant validity was found. Test–retest stability over 6 months was satisfactory. Results support the reliability and validity of the Finnish adaptation of the SAS-A, and further indicate that gender differences in adolescents’ social anxiety may vary across Western countries.     

Measurement invariance of the Schizotypal Personality Questionnaire-Brief across gender and age

The purpose of this study was to examine the dimensional structure and measurement invariance of the Schizotypal Personality Questionnaire-Brief (SPQ-B) (Raine and Benishay, 1995) across sex and age in a representative sample of nonclinical adolescents and young adults. The sample consisted of 1789 adolescents and young adults (42.1% males), with a mean age of 17.1years (S.D.=2.9). The results indicated that the Likert version of the SPQ-B showed adequate psychometric properties (α total score 0.89). The schizotypal personality models that presented the best fit indices were Raine et al.'s (1994) three-factor model and Stefanis et al.'s (2004) four-factor model. In addition, the results support the measurement invariance of the SPQ-B across sex and age. When the latent means of the schizotypal dimensions were compared across sex and age, statistically significant differences were found. Consistent with previous literature, schizotypal personality is a multidimensional construct whose structure appears invariant across sex and age. Future studies should examine the invariance of schizotypal personality across cultures, as well as using the SPQ-B as a screening method in the general population to detect individuals at risk for schizophrenia-spectrum disorders, given its rapid and easy administration.     

Anger expression in Swiss adolescents: establishing measurement invariance across gender in the AX scales

The present study examined measurement invariance in the three anger expression subscales of the STAXI (Spielberger, 1988) with respect to gender. In a sample of 576 male and 531 female students, strict measurement invariance was found. For all three anger expression factors, no differences in variances or factor correlations were found. A large negative relation between Anger-Out and Anger-Control emerged. Girls reported significantly lower levels in Anger-Out and Anger-Control than boys. Results suggest that the questionnaire functions the same way across gender. Also, boys and girls exhibited the same range of interindividual differences in anger expression. The negative relation between Anger-Out and Anger-Control suggests that high levels of Anger-Out might be an obstacle in controlling anger. Lower levels of Anger-Out and -Control in girls suggest that girls might need less control because they express anger less outwardly.     

Factor Structure of the Liebowitz Social Anxiety Scale for Children and Adolescents

The purpose of this study was to evaluate the factor structure of the Liebowitz Social Anxiety Scale for Children and Adolescents (LSAS-CA). The LSAS-CA was administered to 225 children and adolescents as a component of various clinical studies. In addition, other measures of psychopathology and impairment were administered to a subgroup of the sample. Confirmatory factor analyses of the social interaction and performance subscales for the anxiety and avoidance ratings yielded poor fit indices. Exploratory factor analysis supported a two-factor solution with a higher order factor for the LSAS-CA anxiety and avoidance ratings. Based on item content, factors were named Social and School Performance. The internal consistency of the factors was high and the convergent and divergent validity was supported vis-à-vis correlations with measures of depression and social anxiety, and clinician ratings of impairment and functioning. Findings suggest that the anxiety and avoidance ratings are best explained by a two-factor solution that measures social anxiety and avoidance in social and school performance interactions. This factor structure appears to be a reliable and valid framework for assessing childhood social phobia.This research was funded by a grant from SmithKline Beecham to Drs. Liebowitz and Masia-Warner. The authors would like to thank Heather Dent and Sharon Davies for their contributions to the execution of this study.     

Personality and suicidal ideation in the elderly: factorial invariance and latent means structures across age

Objectives: Suicide among the elderly is a dramatic global health problem. Although fatal attempts are frequent in the elderly, research indicated that they rarely present long-term elaboration of suicidal ideation and communicate their intents. Consequently, risk factor detection and assessment are salient. Although evidence on the association between personality and suicidal ideation in young adults is accumulating, little is known about its relevance in the elderly. The purpose of the present study was to analyze the components of a measurement model that are invariant across young adults and older adults and then investigate the relations among dimensions of personality and suicide risk. We postulated a specific relation pattern a priori and tested the hypotheses statistically in order to examine the models for equivalency of the factorial measurement.

Method: We investigated 316 young adults and 339 older adults, who were administered self-report questionnaires to assess depression, hopelessness, alternative five-factor model of personality, and self–other perception.

Results: Multigroup confirmatory factor analyses were conducted, yielding a final model with excellent fit to the data. This model showed a similar pattern of associations between suicidal ideation and personality across both groups.

Conclusions: Although the elderly are exposed to specific life stressors associated with suicidal ideation, our findings suggest that the elderly and young adults may be similar on personality and psychopathology variables predicting suicidal ideation than previously hypothesized. Implications are provided for enhanced assessment and intervention of the elderly high in neuroticism, depression, hopelessness, and with negative self–other perception.     

Psychometric evaluation of the Social Anxiety Scale for Adolescents and the Social Phobia and Anxiety Inventory for Children: construct validity and normative data

This study evaluated the psychometric properties of the Social Anxiety Scale for Adolescents (SAS-A) and Social Phobia and Anxiety Inventory for Children (SPAI-C) in a sample of 1147 adolescents aged 13-17 years. The fit indices of confirmatory factor analyses were comparable to those obtained in prior studies and supported the hypothesized models of the SAS-A and SPAI-C. The internal consistency was good and 12-month test-retest reliability modest for both measures. A significant, positive correlation was found between the SAS-A and SPAI-C, showing that these measures assess related, but relatively independent constructs of social anxiety and phobia. These findings support the use of the SAS-A and SPAI-C with adolescents.     

Cross validation of the Social Anxiety Scale for Adolescents in a high school sample

Social anxiety disorder in adolescents is increasingly recognized as a common condition that may precede onset of other mental health problems. However, few measures are currently available to screen for adolescent social anxiety, and little is known about their psychometric characteristics in school-based samples. To this end, the present study was undertaken as a psychometric cross validation of the Social Anxiety Scale for Adolescents (SAS-A). Exploratory and Confirmatory Factor Analyses (CFA) supported the original 3-factor structure of the SAS-A but retained fewer items than in the original scale. The revised scales demonstrated good internal consistency as well as criterion and concurrent validity. Despite including fewer items, psychometric characteristics of the revised scales were equivalent to or stronger than those reported in previous studies of the measure. As such, the present study provides initial support for the utility of the revised SAS-A as a measure of social anxiety in adolescent school samples.     

Reliability and Validity of the Chinese Version of the Social Anxiety Scale for Adolescents

This study evaluated the psychometric properties of the Chinese version of the Social Anxiety Scale for Adolescents (SAS-A) in a sample of 296 adolescents (49% boys) in Grades 7, 8, 9, 10, and 12 with a mean age of 15.52 years. Confirmatory factor analysis replicated the three-factor structure of the SAS-A in the Chinese sample: Fear of Negative Evaluation (FNE), Social Avoidance and Distress in New Situations (SAD-New), and Social Avoidance and Distress-General (SAD-General). Internal consistency and test-retest reliability were appropriate. The results also revealed a clear and predictable pattern of relationships between the SAS-A and the Questionnaire about Interpersonal Difficulties for Adolescents and the International Personality Item Pool. Chinese boys reported greater SAD-General than Chinese girls, and this difference increased with grade. The SAS-A scores were compared to previously collected data from the USA and Spain, revealing that Chinese adolescents scored significantly higher in social anxiety than American and Spanish adolescents.     

The validity of the Schizotypal Personality Questionnaire in a Greek sample: Tests of measurement invariance and latent mean differences

BackgroundThe Schizotypal Personality Questionnaire (SPQ) is a widely used scale for measuring schizotypal characteristics modeled on DSM-III-R criteria for schizotypal personality disorder (SPD). The aim of this study was to examine the factorial structure of the Greek SPQ, its factorial invariance across gender and different age groups and possible gender and age group differences at latent mean level.MethodsEight hundred sixty-five community participants completed the Greek version of the SPQ.ResultsWith regard to the factorial structure of the original first-order model, the results showed that a seven-factor model (sub-scales “no close friends” with “constricted affect” and “ideas of reference” with “unusual perceptual experiences” were combined) was replicated adequately. Furthermore, the second-order “paranoid” model provided also adequate fit. With regard to the factorial invariance of the SPQ across gender and age, the analysis revealed that both, the first- and second-order models showed measurement invariance (configural, metric and structural) across gender and age groups (17–35 vs. 36–70). Latent mean differences across gender and age groups were also found.ConclusionsBased on these findings, we can conclude that the Greek version of the SPQ is a psychometrically sound instrument for measuring schizotypal characteristics and a useful screening tool for SPD across gender and age.     

The Social Anxiety Scale for Adolescents: Measurement Invariance and Psychometric Properties Among a School Sample of Portuguese Youths

Over the last decades there has been an increased interest in assessing social anxiety in adolescents. This study aims to validate the Social Anxiety Scale for Adolescents (SAS-A) to Portuguese youth, and to examine its invariance across gender as well as its psychometric properties. The participants were 782 Portuguese youths (371 males, 411 females), with an average age of 15.87 years (SD = 1.72). The results support the original three-factor structure of the SAS-A, with measurement invariance being found across gender, with females scoring higher than males on two subscales. High levels of internal consistency were found. Positive associations with empathy demonstrated that high socially anxious adolescents have elevated empathy tendencies. Mostly null or low negative associations were found with measures of psychopathic traits, callous-unemotional traits and aggression. Study findings provide evidence that the SAS-A is a psychometrically sound instrument that shows measurement invariance between genders, good reliability and positive correlations with empathy.     

The Factor Structure of the Liebowitz Social Anxiety Scale for Children and Adolescents: Development of a Brief Version

The Liebowitz Social Anxiety Scale for Children and Adolescents (LSAS-CA-SR) is a validated instrument for the assessment of social anxiety in youth. The three main objectives of the present study were to (a) examine the factor structure of the LSAS-CA-SR; (b) to validate the factors against relevant personality measures, and (c) to create a brief and reliable version of the questionnaire. A total of 1,362 adolescents completed self-report measures of social anxiety, temperament, character and personality traits. The factor structure was examined using a combination of confirmatory and exploratory factor analysis. The analysis was conducted on both the anxiety and avoidance sub-scales, and identical items for both sub-scales were maintained. Two factors emerged: social interaction and school performance. These factors demonstrated high internal consistency and a significant correlation with relevant self-report measures. A brief version comprised of 14 items was highly correlated (0.96) with the full version. The new factor structure represents advancement over the previous efforts, and holds promise for efficient utilization of the LSAS-CA.     

Attachment and self-evaluation in Chinese adolescents: Age and gender differences

This study investigated age and gender differences in the quality of attachment to mothers, fathers, and peers, and the association of attachment with measures of self-evaluation in 584 Chinese adolescents in junior high, high school, and university. Their responses to the Inventory of Parent and Peer Attachment indexed attachment quality, and self-evaluation was measured by the Rosenberg Self-Esteem Scale and the Self-Liking and Self-Competence Scale. Consistent with findings with Western samples, our analyses revealed (a) lower parent–child relationship quality in middle (compared to early) adolescence, (b) a significant association of parental and peer attachment with self-evaluation, and (c) gender differences in attachment to peers, with females reporting stronger attachment than males. Chinese females reported stronger maternal attachment than did males, and for females the quality of maternal attachment was more strongly related to self-evaluation than any other attachment relationship. During high school, peer attachment quality – rather than parental – was preeminently associated with self-evaluation. The findings of this study indicate that in a context of considerable consistency of findings with Western studies, parent–child attachment in Chinese adolescents is also influenced by culture-specific practices that influence parent–youth relationships and their meaning to the child.     

Exploration of the psychometric characteristics of the Liebowitz Social Anxiety Scale in a Spanish adolescent sample

Social phobia is an excessive concern about scrutiny by other people in situations the person considers embarrassing or humiliating. The purpose of this study is to explore the factor structure, reliability, and validity of the social fear and social avoidance subscales of the Liebowitz Social Anxiety Scale (LSAS) and to analyze the score distribution of both subscales. To this end, we assessed a sample of 1,012 Spanish adolescents attending school. The results of a first-order factor analysis indicate the existence of a dominant factor in both subscales of the LSAS--as well as three other less relevant factors--and explain most of the variance of the subscales. The internal consistency of the first factor was quite high in both subscales. The LSAS and its two subscales showed adequate theoretical validity with different variables related to social interaction. Finally, the different scores obtained in both subscales make it possible to group adolescents into three clusters with different characteristics. A study of the sociodemographic variables of the components of the clusters showed a significant relation only with sex.     

Exploring age and gender differences in health risk behaviours and psychological functioning among homeless children and adolescents

This study describes the findings from quantitative examination of age and gender differences in psychological problems and health risk behaviour among 227 homeless youth. The findings indicated significant variations on health risk behaviours by gender. As compared to males, females were more likely to engage in survival sex, been victims of violence-rated sex, and more likely to have made a plan to commit suicide. While alcohol use decrease with age, marijuana use and having multiple sexual partners, on the other hand, increases with age. Approximately 87% of the participant’s exhibit moderate-to-severe psychological problems, with males having significantly higher scores on the overall psychological well-being, emotional and hyperactivity problems than females. Age-group differences were also observed on overall psychological well-being, emotional problems, conduct problems and hyperactivity. These findings from the study are discussed with reference to previous research and implications for interventions are provided.     

Psychometric properties of the Malay Schizotypal Personality Questionnaire: Measurement invariance and latent mean comparisons in Malaysian adults

Introduction

The Schizotypal Personality Questionnaire (SPQ) is a widely used self‐report measurement instrument for the assessment of schizotypal personality traits. However, the factor structure of the SPQ has been a matter of some debate. As a contribution to this debate, we examined the factor structure of the SPQ in Malaysian adults.

Method

A total of 382 Malaysian adults completed a Malay translation of the SPQ. Confirmatory factory analysis was used to examine the fit of 3‐ and 4‐factor solutions for the higher‐order dimensionality of the SPQ. Ethnic invariance for the best‐fitting model was tested at the configural, metric, and scalar levels, and a multivariate analysis of variance was used to examine sex and ethnicity differences in domain scores.

Results

The 4‐factor model provided a better fit to the data than did the 3‐factor model. The 4‐factor model also demonstrated partial measurement invariance across ethnic groups. Latent mean comparisons for sex and ethnicity revealed a number of significant differences for both factors, but effect sizes were small.

Discussion

The 4‐factor structure of the SPQ received confirmatory support and can be used in Malay‐speaking populations.     

A study on gender and age differences in sleep spindles

In the present work, gender differences in sleep spindle topography were examined in 40 subjects. Their median age was 32 years (range 22-49 years). Spindles were detected from 3,306,060 s of visually scored stage 2 sleep EEG by a previously validated automatic fuzzy detector at 1-second intervals. A total of 271,168 spindles were found from the six EEG channels analyzed. Females showed a significantly higher percentage of spindles in the left frontal channel than males (Fp1-A2; p = 0.026). To confirm that this difference was gender and not age related, the subjects were divided into two age groups. No significant differences in spindle activity of the frontal channels were found between the groups. However, the interindividual spindle variability seemed to be at least as large as that stemming from gender.     

Social Anxiety in High-functioning Children and Adolescents with Autism and Asperger Syndrome

We examined social anxiety and internalizing symptoms using the Social Phobia and Anxiety Inventory for Children (SPAI-C), the Social Anxiety Scale for Children -Revised (SASC-R), and the Child Behavior Checklist (CBCL) in a sample of fifty-four high-functioning subjects with autism or Asperger syndrome (HFA/AS) (M = 11.2 ± 1.7 years) and 305 community subjects (M = 12.2 ± 2.2 years). Children and adolescents completed the SPAI-C and SASC-R, and their parents completed the CBCL Internalizing scale. Adolescents with HFA/AS scored higher than the community sample on all measures. Behavioural avoidance and evaluative social anxiety increased by age within the HFA/AS group, whereas behavioural avoidance decreased by age in control participants. Data support that HFA/AS in adolescents may be associated with clinically relevant social anxiety symptoms.     

Adolescents with gender identity disorder: reconsideration of the age limits for endocrine treatment and surgery

The third versions of the guideline for treatment of people with gender identity disorder (GID) of the Japanese Society of Psychiatry and Neurology does not include puberty-delaying hormone therapy. It is recommended that feminizing/masculinizing hormone therapy and genital surgery should not be carried out until 18 year old and 20 year old, respectively. On the other hand, the sixth (2001) and the seventh (2011) versions of the standards of care for the health of transsexual, transgender, and gender nonconforming people of World Professional Association for Transgender Health (WPATH) recommend that transsexual adolescents (Tanner stage 2, [mainly 12-13 years of age]) are treated by the endocrinologists to suppress puberty with gonadotropin-releasing hormone (GnRH) agonists until age 16 years old, after which cross-sex hormones may be given. A questionnairing on 181 people with GID diagnosed in the Okayama University Hospital (Japan) showed that female to male (FTM) transsexuals hoped to begin masculinizing hormone therapy at age of 15.6 +/- 4.0 (mean +/- S.D.) whereas male to female (MTF) transsexuals hoped to begin feminizing hormone therapy as early as age 12.5 +/- 4.0, before presenting secondary sex characters. After confirmation of strong and persistent cross-gender identification, adolescents with GID should be treated with cross-gender hormone or puberty-delaying hormone to prevent developing undesired sex characters. These treatments may prevent transsexual adolescents from attempting suicide, being depressive, and refusing to attend school. Subsequent early breast and genital surgery may help being employed in desired sexuality.
