Dimensions of maltreated children's home behavior: A factor analytic approach

This study identified dimensions of home behavior of maltreating parents and their children through exploratory factor analysis. Five child factors were identified: self-directed behavior, affiliative behavior, negativity, positive social interaction, and questioning. Five parent factors were identified: positive social interaction, caretaking, discipline, refusal, and hostility. Multivariate analyses indicated that neglected children and abused children had less positive social interaction than adequately reared children. Children showed more questioning and less negativity at older ages. Abusing parents were most hostile, whereas neglecting parents showed the least positive social interaction. Abusing parents directed less hostility toward older children than the other child-rearing groups. Parents exhibited less caretaking behavior toward older children and directed more positive social interaction toward children with higher developmental quotients. The results suggest that factor analysis is a viable means of identifying dimensions of child and parent behavior which could facilitate comparison of effects across studies.     

The structure of temperament in preschoolers: a two-stage factor analytic approach

The structure of temperament traits in young children has been the subject of extensive debate, with separate models proposing different trait dimensions. This research has relied almost exclusively on parent-report measures. The present study used an alternative approach, a laboratory observational measure, to explore the structure of temperament in preschoolers. A 2-stage factor analytic approach, exploratory factor analyses (n = 274) followed by confirmatory factor analyses (n = 276), was used. We retrieved an adequately fitting model that consisted of 5 dimensions: Sociability, Positive Affect/Interest, Dysphoria, Fear/Inhibition, and Constraint versus Impulsivity. This solution overlaps with, but is also distinct from, the major models derived from parent-report measures.     

The psychopathology of anorexia nervosa: A factor analytic investigation

To examine the psychopathology of anorexia nervosa, behavioral assessment measures sampling a wide range of relevant constructs were collected on 150 women diagnosed as having anorexia nervosa. The data were subjected to an exploratory factor analysis using maximum-likelihood estimation and oblique rotation. Five factors were extracted, which were titled Fasting and Restrictive Eating, Depression, Anxiety, and Negative Self-image, Bulimic Behaviors, Fear of Fatness/Body Image Disturbance, and Impulsive Behavior/Post-Traumatic Response. Discriminate function analysis suggested that, other than the bulimic behaviors factor, the Impulsive Behavior/Post-Traumatic Response factor best discriminated between bulimic and restrictor subtypes of anorexics. These data suggest that the underlying dimensions of anorexia nervosa are very similar to those of bulimia nervosa. The findings also have implications for the multidimensional assessment and treatment of anorexia nervosa as well as conceptual models of the disorder.     

The psychometric properties of the internet addiction test.

There is growing concern about excessive Internet use and whether this can amount to an addiction. In researching this topic, a valid and reliable assessment instrument is essential. In her survey of Internet addiction, Young designed the Internet Addiction Test (IAT), which provides a basis for developments. The IAT has high face validity, but it has not been subjected to systematic psychometric testing. This study sought to replicate and expand Young's survey, and to examine the IAT more systematically. A questionnaire that existed as a Web page was devised, consisting of the IAT and 15 other questions regarding the respondents' demographic information and Internet usage. Participants were recruited through the Internet, yielding 86 valid responses (29 males and 57 females). Factor analysis of the IAT revealed six factors--salience, excessive use, neglecting work, anticipation, lack of control, and neglecting social life. These factors showed good internal consistency and concurrent validity, with salience being the most reliable. Younger and more recent users reported more problems, mainly concerning the neglect of work and social life. We expected interactive Internet functions to be more addictive; however, this was not found to be so. Overall, the IAT is a valid and reliable instrument that may be used in further research on Internet addiction.     

A factor analytic study of the psychological implications of the computer for the individual and society

The coming of the computer age has provided widespread discussion of the effects on the individual and society of this most recent and powerful intellectual and technological revolution. Discussions of the psychological implications of the computer have produced a literature that is primarily polemic and, in any case, not measurement oriented with respect to identifying basic issues and central attitudes. In this article, measurement procedures including the development and testing of the Cybernetics Attitude Scale (the computer’s psychological effect in each of 10 sectors of society) and a factor analytic study of the collected data are presented. The article concludes with a discussion of the research implications of the factor analytic findings and the ways in which these findings illumine the problem of the meaning of the computer for the individual and society.     

Exploring adolescent social media and internet gaming addiction: The role of emotion regulation

Behavioral addictions such as social media addiction and internet gaming disorder are prevalent among adolescent populations. Although studies have investigated predictors of these addictive behaviors with international samples of adolescents, less is known about American adolescents. In this study, we investigated the predictive nature of emotion regulation after controlling for age, gender, and race with regard to social media addiction and internet gaming disorder severity. Results indicate that gender and emotion regulation significantly predicted both forms of behavioral addictions with small to moderate effects. Specifically, female gender and lower emotion regulation significantly predicted social media addiction and male gender and lower emotion regulation significantly predicted internet gaming disorder severity. Implications for mental health professionals are discussed.     

Shyness and locus of control as predictors of internet addiction and internet use.

The new psychological disorder of Internet addiction is fast accruing both popular and professional recognition. Past studies have indicated that some patterns of Internet use are associated with loneliness, shyness, anxiety, depression, and self-consciousness, but there appears to be little consensus about Internet addiction disorder. This exploratory study attempted to examine the potential influences of personality variables, such as shyness and locus of control, online experiences, and demographics on Internet addiction. Data were gathered from a convenient sample using a combination of online and offline methods. The respondents comprised 722 Internet users mostly from the Net-generation. Results indicated that the higher the tendency of one being addicted to the Internet, the shyer the person is, the less faith the person has, the firmer belief the person holds in the irresistible power of others, and the higher trust the person places on chance in determining his or her own course of life. People who are addicted to the Internet make intense and frequent use of it both in terms of days per week and in length of each session, especially for online communication via e-mail, ICQ, chat rooms, newsgroups, and online games. Furthermore, full-time students are more likely to be addicted to the Internet, as they are considered high-risk for problems because of free and unlimited access and flexible time schedules. Implications to help professionals and student affairs policy makers are addressed.     

The analytic group: A multifaceted approach to the treatment of adolescents

During adolescence the peer group plays a major role in facilitating developmental processes, since it not only serves as a replacement for childhood love-objects and attachments, but offers the adolescent allies in the struggle to separate and become emancipated from parents. For those adolescents who, because of interpersonal and intrapsychic difficulties, have no peer group or have chosen an inappropriate peer group, providing a therapeutic group can make it possible for development to proceed. This paper presents not only a theoretical basis for the utilization of groups of peers in the treatment of adolescents, but also an elaboration on the dynamic processes which make possible improvement of ego-functioning and resolution of core conflicts related to the past, as well as to this particular developmental phase.     

A multitrait-multisource confirmatory factor analytic approach to the construct validity of ADHD rating scales

Confirmatory factor analysis was used to model a multitrait-multisource design to evaluate the construct validity of attention-deficit/hyperactivity disorder (ADHD) rating scales. The 2 trait factors were the ADHD inattention and hyperactivity/impulsivity dimensions. The 2 source factors were parents and teachers. In Study 1, parents and teachers rated 1,475 Australian elementary school children on the ADHD symptoms. In Study 2, parents and teachers rated 285 Brazilian elementary school children on the ADHD symptoms. Similar results occurred in both studies with most of the ADHD symptoms containing more source than trait variance, thus providing weak evidence for the convergent and discriminant validity of the symptoms as measured by rating scales. The study outlines the implications of such strong source effects for understanding ADHD.     

Comparability of peer-assessment measures: A multitrait-multimethod and selection analytic approach

This research attempted to assess the relationship among the Pupil Evaluation Inventory (PEI), sociometric nominations, and sociometric ratings in terms of (1) a multitrait-multimethod analysis, (2) selection agreement indices of extreme individuals, and (3) stability over an 8-week period. Subjects were members of four second-grade classrooms at a regional school serving a diverse population of children. While stability estimates for measures were adequate and evidence for convergent validity was reasonably good, evidence for divergent validity was weaker. Selection agreement analyses yielded highly variable results, indicating that different samples of children tend to be selected by different instruments despite the similarity in dimensions being tapped. Methodological and theoretical implications of these findings are discussed.This work was based on the first author's M.S. thesis under the direction of the second author.     

A confirmatory factor analytic approach on perceptions of knowledge and skills in teaching (PKST)

This paper reports the cross-validation of the factor pattern of the Perceptions of Knowledge and Skills in Teaching (PKST) survey, which was used to assess the self-perceived pedagogical knowledge and skills of pre-service and beginning teachers. The sample comprised 323 pre-service teachers enrolled in a 1-yr. post-graduate teacher education program in Singapore. The survey had 37 items distributed across six scales: student learning, lesson planning, instructional support, accommodating diversity, classroom management, and care and concern. A confirmatory factor analysis (CFA) was used to cross-validate the survey's factor pattern. The results showed that the model was an acceptable fit to the data. The PKST survey can thus be adapted by different teacher education programs to assess pre-service and beginning teachers' progress in developing their pedagogical knowledge and skills.     

Implicit and explicit self-esteem in the context of internet addiction

Previous research has repeatedly found that people suffering from some clinical disorders (e.g., bulimia nervosa, depression) possess low explicit (i.e., conscious, deliberate) self-esteem while at the same time displaying high implicit (i.e., unconscious, automatic) self-esteem. This phenomenon has been termed damaged self-esteem and was proposed to be an indicator of psychological distress. Although Internet addiction has been found to be associated with low levels of explicit self-esteem, as well as with high levels of psychological distress, its relation to implicit self-esteem has, to our knowledge, not been investigated thus far. We therefore hypothesized that the phenomenon of damaged self-esteem could also be found amongst people suffering from Internet addiction, and conducted two studies using the Initial Preference Task as a measure of implicit self-esteem. As expected, we found that individuals scoring high on Internet addiction possess low explicit and high implicit self-esteem. This effect was, however, only found for the first name initial of the Initial Preference Task, leading to the conclusion that first and last name initials might tap into different parts of implicit self-esteem.     

The expression of feelings as assertive behavior: A factor analytic extension of PRI

The aims of the study were to construct two assertiveness measures, expression of positive feeling and expression of hostile feeling, and to establish their factor analytic independence. One hundred and ninety-seven adults were administered the PRI along with the two new scales. The correlations of the 40 items of the two scales were first analyzed separately to identify the two hypothesized constructs. The five scale scores of the PRI (Defense of Rights, Social Assertiveness. Directiveness, Independence and Approval Seeking) were divided into half-scale scores on the basis of keying (the sums of true-keyed and false-keyed items), and then intercorrelated with the half-scale scores of the new scales. A principal components analysis demonstrated the presence of the six dimensions hypothesized and a measure of validity.
