SPSS programs for the measurement of nonindependence in standard dyadic designs

Dyadic research is becoming more common in the social and behavioral sciences. The most common dyadic design is one in which two persons are measured on the same set of variables. Very often, the first analysis of dyadic data is to determine the extent to which the responses of the two persons are correlated—that is, whether there is nonindependence in the data. We describe two user-friendly SPSS programs for measuring nonindependence of dyadic data. Both programs can be used for distinguishable and indistinguishable dyad members. Inter1.sps is appropriate for interval measures. Inter2.sps applies to categorical variables.

Adolescent Place Attachment, Social Capital, and Perceived Safety: A Comparison of 13 Countries

In adolescence, children become increasingly independent and autonomous, and spend more time in neighborhood settings away from home. During mid-to-late adolescence, youth often become more critical about the place they live. Their attachment to home and even community may decrease as they explore and develop new attachments to other specific places. The aim of this study is to understand how 15-year-old students from 13 countries perceive their local neighborhood area (place attachment, social capital and safety), and how these different community cognitions are interrelated. We hypothesize that their place attachment predicts safety, and that the relationship is mediated in part by social capital. Result show that, despite cross-cultural differences in neighborhood perceptions, the proposed theoretical model fits robustly across all 13 countries.     

Effects of Self-Consciousness and Social Anxiety on Self-Disclosure among Unacquainted Individuals: An Application of the Social Relations Model

Recent research has demonstrated a positive relationship between private self-consciousness and the tendency to self-disclose. These studies have relied exclusively upon self-reports of disclosure. In the present study, Kenny's Social Relations Model (Kenny & La Voie, 1984) was employed to examine the relationship between a subject's self-reports and others' reports of a subject's level of self-disclosure and the relationship of these reports to private self-consciousness, as well as the other traits measured by the self-consciousness scale: public self-consciousness and social anxiety. Unacquainted college women (N = 102) participated in one-on-one interactions in a round-robin design. Subject's self-reports of disclosure and their levels of private self-consciousness correlated positively. The partners' reports of an individual's disclosure, however, were not related to the individual's level of private self-consciousness. The discrepancy between these correlations emphasizes the necessity to ground research in personal relationships on interacting pairs and not only on the self-reports of one member. Future research that would explore this difference is discussed. The examination of the self- and partner reports and subjects' levels of public self-consciousness and social anxiety demonstrated that these two traits significantly influence the acquaintance process. Public self-consciousness related positively to subjects' beliefs that they had created consistent impressions upon their partners. Social anxiety correlated negatively with partners' reports of a subject's dyadic involvement and openness.     

Child characteristics,family demographics and family processes: Their effects on the stress experienced by families of children with disabilities

Parents of children with disabilities are often reported as having more stress than their counterparts. Because past investigations of parent stress have been limited by considering too few sources of stress, this study gathered a large variety of demographic, child and family process variables. Two domains of parenting stress, including those aspects related to the child's characteristics (child related) and those aspects concerned with the parent's attitudes toward parenting (parent related) were analyzed separately. The results showed that the circumstances and processes of a family, as well as child characteristics, must be taken into account when clinicians attempt to mediate problems. This research has direct application for clinicians and interventionists. If intervention hopes to truly serve families, a thorough understanding of parenting stress is needed.     

Visual-motor problems of adolescents who attempt suicide.

Using the Canter Background Interference Procedure with the Bender-Gestalt Test, a group of 18 adolescent suicide attempters earned test scores indicating they had significantly more problems with visual-motor coordination than did a control group of 21 adolescents. There were also a greater number of school failures and behavior problems among these suicide attempters. The findings suggest that learning disabilities may be an unrecognized factor which increases the risk of suicide attempts by adolescents.     

Understanding the effects of sample size on the variability of the mean

In the first three experiments, we attempted to learn more about subjects' understanding of the importance of sample size by systematically changing aspects of the problems we gave to subjects. In a fourth study, understanding of the effects of sample size was tested as subjects went through a computerassisted training procedure that dealt with random sampling and the sampling distribution of the mean. Subjects used sample size information more appropriately for problems that were stated in terms of the accuracy of the sample average or the center of the sampling distribution than for problems stated in terms of the tails of the sampling distribution. Apparently, people understand that the means of larger samples are more likely to resemble the population mean but not the implications of this fact for the variability of the mean. The fourth experiment showed that although instruction about the sampling distribution of the mean led to better understanding of the effects of sample size, subjects were still unable to make correct inferences about the variability of the mean. The appreciation that people have for some aspects of the law of large numbers does not seem to result from an in-depth understanding of the relation between sample size and variability.     

Using trait–state models to evaluate the longitudinal consistency of global self-esteem from adolescence to adulthood

The present research used a latent variable trait–state model to evaluate the longitudinal consistency of self-esteem during the transition from adolescence to adulthood. Analyses were based on ten administrations of the Rosenberg self-esteem scale (Rosenberg, 1965) spanning the ages of approximately 13–32 for a sample of 451 participants. Results indicated that a completely stable trait factor and an autoregressive trait factor accounted for the majority of the variance in latent self-esteem assessments, whereas state factors accounted for about 16% of the variance in repeated assessments of latent self-esteem. The stability of individual differences in self-esteem increased with age consistent with the cumulative continuity principle of personality development.     

Preliminary support for links between media body ideal insecurity and women's shoe and handbag purchases

Two studies examined the relationship between women's insecurity-arousing comparisons with female models and shoe/handbag ownership. Idealized media images appear capable of threatening some women's sense of attractiveness and it may be that as a result, accessorizing becomes particularly appealing because it helps increase physical attractiveness without drawing attention to one's figure, the object of the threatening comparisons. In Study 1 (N=922), a correlational study, the more women reported that they feel insecure when they see attractive female models, the more shoes they tended to own. In Study 2 (N=286), we manipulated whether women saw images of attractive female models or not. The more women exhibited insecurity following exposure to the images of attractive models, the more shoes and handbags they tended to own. In both studies, these effects did not hold for ownership of trousers, an item of clothing that draws attention toward one's body.     

The common fate model for dyadic data: variations of a theoretically important but underutilized model

Studying dyads, very often there is a theoretical construct that has an effect on both members, such as relationship harmony or shared environment. To model such influences, the common fate model (CFM) is often the most appropriate approach. In this article, we address conceptual and statistical issues in the use of the standard CFM and present a series of variations, all of which are estimated by structural equation modeling (SEM). For indistinguishable dyad members (e.g., gay couples), we describe the use of a multilevel SEM method. Throughout the paper, we draw connections to the actor-partner interdependence model (APIM). We also discuss the analysis of hybrid models that combines both the CFM and the APIM. The models are illustrated using data from heterosexual couples.
