Content analysis: a comparison of manual and computerized systems

Computerized content analysis is a technique for classifying texts. In personality research it has been used to make inferences about psychological states and traits of the speaker or writer. Whereas computerized techniques have been increasing in both sophistication and ease of use, questions remain regarding their validity compared to hand-scored scales. In this study, we compare a relatively simple computerized technique; a more sophisticated, context-sensitive computerized approach; and a context-sensitive, human-scored system. Seventy-one subjects, representing four diagnostic groups, provided free-speech samples which were scored according to all three methods. Data from each method were then submitted to discriminant and classification analyses. In comparing the classification performance of the three methods, we found that both computerized methods were more accurate than the human-scored method. The time and cost benefits of computerized systems are discussed.     

Physician-diagnosed medical disorders in relation to PTSD symptoms in older male military veterans.

The association between physician-diagnosed medical disorders and combat-related posttraumatic stress disorder (PTSD) symptoms was examined in 605 male combat veterans of World War II and the Korean conflict. Physician exams were performed at periodic intervals beginning in the 1960s. PTSD symptoms were assessed in 1990. Cox regression was used to examine the onset of each of 12 disorder categories as a function of PTSD symptoms, controlling for age, smoking, alcohol use, and body weight at study entry. Even with control for these factors, PTSD symptoms were associated with increased onset of arterial, lower gastrointestinal, dermatologic, and musculoskeletal disorders. There was only weak evidence that PTSD mediated the effects of combat exposure on morbidity. Possible mediators of the relationship between combat exposure, PTSD, and physical morbidity are discussed.     

Beauty or function? How different mass customization toolkits affect customers' process enjoyment

Although it is widely acknowledged that mass customization (MC) increases both company and customer value, the research has neglected the possible effects of different MC toolkits on customer responses. In this study, we investigate the influence of different MC toolkits on customers' process enjoyment by manipulating the extent to which those toolkits allow customers to customize a product's functional attributes (functional MC toolkits), aesthetic attributes (aesthetic MC toolkits), or both (supreme toolkits). In addition, we examine the moderating effect of customers' ability to customize. The results of two experimental studies show that regardless of their ability to customize, customers' process enjoyment is higher with an aesthetic MC toolkit than with a functional MC toolkit. For customers with a high ability to customize, process enjoyment with a supreme toolkit is higher than process enjoyment with an aesthetic toolkit, whereas no differences exist for customers with a low ability to customize. This research contributes significantly to the existing literature on mass customization and provides managers with insights on how to more effectively develop and implement MC toolkits.

Change in posttraumatic stress disorder symptoms: do clinicians and patients agree?

This study assessed the longitudinal association between clinician and patient ratings of posttraumatic stress disorder (PTSD) symptoms over the course of 2 different randomized clinical trials of veterans with chronic PTSD. One trial, the Department of Veterans Affairs Cooperative Study 420 (CSP 420; N = 360) compared trauma-focused and present-centered group therapies, and the 2nd trial compared cognitive processing theory and a waitlist control condition (N = 60). Linear mixed effects modeling revealed significant associations between clinician ratings (Clinician-Administered PTSD Scale; CAPS; D. D. Blake et al., 1990) and patient ratings (Posttraumatic Stress Disorder Checklist; PCL; F. W. Weathers, B. T. Litz, J. A. Herman, J. A. Huska, & T. M. Keane, 1993) in total and symptom clusters of PTSD. Contrary to hypothesis, the amount of change on the CAPS ranged from .75 to .82 standard deviations for every 1 standard deviation change on the PCL. The CAPS and PCL were more closely associated in the trauma-focused vs. present-centered treatment condition in CSP 420, and especially regarding hyperarousal symptoms. When comparing categorization of clinically significant change on the CAPS and PCL, the authors found no differences in the percentages of agreement between clinicians and patients in improvement and exacerbation. The value of multimodal assessment of PTSD treatment outcomes is discussed.

Longitudinal Impact of Toddlers' Exposure to Domestic Violence

This study assessed how exposure to domestic violence (DV) during early childhood and increases in exposure over time influenced toddlers' behavior and peer problems, physical health, and cognitive abilities in middle childhood. Data from three waves of the survey component of “Welfare, Children, and Families: A Three-City Study” were assessed. Thirty-five percent of the 2- to 4-year-olds had mothers who reported DV victimization; 16% reported an increase in DV victimization over 2 years. Opposing past literature, none of the middle childhood outcomes were significantly influenced by early DV exposure. However, increases in mother's DV victimization from 1999 to 2001 significantly increased children's internalizing and externalizing problems and marginally decreased their school engagement in middle childhood in 2005.     

Detection of coherence-disrupting and coherence-conferring alterations in text

In a study phase, subjects were presented with sentence pairs which were either coherent or anomalous. In a subsequent recognition test, each sentence pair was presented either in its original form or with one word changed. The changed word either disrupted the coherence of a previously coherent sentence pair or conferred coherence on a previously anomalous sentence pair. Alterations were more accurately detected if they were coherence-disrupting than if they were coherence-conferring. In a coherence-conferring alteration, the altered sentence can be assimilated to one of the abstract cognitive units activated by the studied sentence pair, whereas in a coherence-disrupting alteration, the altered sentence cannot be so assimilated. Analogous asymmetries have been observed for musical sequences that are coherent or anomalous with respect to tonality and rhythm. These parallels suggest that principles of cognitive organization that are responsible for our intuitions of coherence cut across propositional and nonpropositional domains.     

Comparison of TAT and free speech techniques for eliciting source material in computerized content analysis

We compared the free speech samples and Thematic Apperception Test (TAT) responses of 95 community-residing volunteers by using the General Inquirer content analysis computer program and the Harvard III Psychosociological Dictionary (Stone, Dunphy, Smith, & Ogitvie, 1966). Comparability was assessed by computing mean differences and correlations among techniques. The techniques were evaluated by assessing the ability of data derived from each to predict individual differences in developmental level, gender, depressive symptomatology, and personality. Results show highly discriminable profiles and low reliability among techniques. TAT data were superior in predicting individual, differences. We suggest that structured techniques like the TAT are preferable to standard free speech instructions for eliciting data in content analytic studies and discuss the possibility of computerized content analysis as a method of scoring the TAT.     

Trauma in the Lives of Older Men: Findings from the Normative Aging Study

Research on the prevalence of traumatic exposure has tended to focus on younger populations, limiting our knowledge about trauma and its effects in older adults. In this study, lifetime trauma exposure was assessed in a sample of 436 male military veterans of World War II and the Korean Conflict (age 59–92). A clinician-administered screening measure, the Brief Trauma Interview, was developed to assess lifetime exposure to 10 categories of trauma using DSM-IV criteria. PTSD was assessed in interview and questionnaires. Despite a high prevalence of trauma exposure, symptom levels were relatively low. Few men met criteria for current or lifetime PTSD. Secondary analyses found that lifetime symptom severity was higher in men who met the DSM-IV A.2 criterion, in contrast with men who did not meet A.2. Findings indicate that trauma is highly prevalent among older men, although many may be asymptomatic.
