Equivalence of computerized and conventional versions of the Beck Depression Inventory-II (BDI-II)

This study examined the equivalence of the conventional and computerized versions of the Beck Depression Inventory-II (BDI-II), taking into account that computer aver-sion may negatively impact computer-administered BDI-II scores by elevating them. Participants were 180 psychology undergraduate students from a medium-sized midwestern university. Participants were divided into four experimental groups. Each group was administered the BDI-II twice in various combinations (conventional only, computerized only, conventional and computerized and vice versa). All participants completed measures of computer aversion and computer experience. Participants who received both versions of the BDI-II were also asked to specify their preference for method of administration. Independent samples t-test results indicated that the com-puterized and paper-and-pencil versions of the BDI-II may be considered equivalent in terms of measurement validity. Implications for future research are discussed. Portions of this article were presented at the 1999 meetings of the American Psychological Association, Boston.

Optimizing the number of steps in learning tasks for complex skills

Background. Carrying out whole tasks is often too difficult for novice learners attempting to acquire complex skills. The common solution is to split up the tasks into a number of smaller steps. The number of steps must be optimized for efficient and effective learning. Aim. The aim of the study is to investigate the relation between the number of steps provided to learners and the quality of their learning of complex skills. It is hypothesized that students receiving an optimized number of steps will learn better than those receiving either the whole task in only one step or those receiving a large number of steps. Sample. Participants were 35 sophomore law students studying at Dutch universities, mean age = 22.8 years (SD=3.5), 63% were female. Method. Participants were randomly assigned to 1 of 3 computer‐delivered versions of a multimedia programme on how to prepare and carry out a law plea. The versions differed only in the number of learning steps provided. Videotaped plea‐performance results were determined, various related learning measures were acquired and all computer actions were logged and analyzed. Results. Participants exposed to an intermediate (i.e. optimized) number of steps outperformed all others on the compulsory learning task. No differences in performance on a transfer task were found. A high number of steps proved to be less efficient for carrying out the learning task. Conclusions. An intermediate number of steps is the most effective, proving that the number of steps can be optimized for improving learning.     

The equivalence of computerized and paper-and-pencil psychological instruments: Implications for measures of negative affect

The use of computerized psychological assessment is a growing practice among contemporary mental health professionals. Many popular and frequently used paper-and-pencil instruments have been adapted into computerized versions. Although equivalence for many instruments has been evaluated and supported, this issue is far from resolved. This literature review deals with recent research findings that suggest that computer aversion negatively impacts computerized assessment, particularly as it relates to measures of negative affect. There is a dearth of equivalence studies that take into account computer aversion’s potential impact on the measurement of negative affect. Recommendations are offered for future research in this area.     

Effects of Changed Item Order: A cautionary note to practitioners on jumping to computerized adaptive testing for personality assessment

This study aims to investigate the effects of item order used with computerized adaptive testing (CAT) in the domain of personality assessment. Based on items from the German version of the Eysenck Personality Profiler, four test versions were designed from seven scales and presented to four experimental groups (n=362). One conventional and three adaptive versions were created, each beginning with items representing either medium or extreme trait levels. Results showed significant differences in average gained person parameters for three out of seven scales between the adaptive versions, as well as differences in average reaction times for answering the items. Results indicated context effects as a problem for using CAT to measure personality.     

Use of the Beck Depression Inventory-II with Adolescent Psychiatric Outpatients

To provide information on the use of the Beck Depression Inventory-II (BDI-II) with adolescents, the BDI-II was administered to 105 male and 105 female outpatients between 12 and 18 years old who were seeking psychiatric treatment. The internal consistency of the BDI-II was high (coefficient = .92). The mean BDI-II total score of the girls was approximately 5 points higher than that of the boys (p < .001), and age (years) was positively correlated with the BDI-II total scores (r = .18, p < .01). An iterated principal-factor analysis identified three factors, but only the Cognitive and Somatic-Affective factors were generalizable.     

Assessing Young Children's Number Magnitude Representation: A Comparison Between Novel and Conventional Tasks

Previously, researchers have relied on asking young children to plot a given number on a 0-to-10 number line to assess their mental representation of numbers 1 to 9. However, such a (“conventional”) number-to-position (N-P) task may underestimate the accuracy of young children's magnitude estimates and misrepresent the nature of their number representation. The purpose of this study was to compare young children's performance on the conventional N-P task and a “modified” N-P task that is more consistent with a discrete-quantity view of number and with measures of theoretically related mathematical competencies. Participants (n = 45), ranging in age from 4;0 to 6;0, were administered both versions of the N-P task twice during 4 sessions in 1 of 2 randomly assigned and counterbalanced orders. Between and within conditions, children were significantly more accurate on the modified version than on the conventional task. The results indicate that the conventional task, in particular, may be confusing and that several simple modifications can make it more understandable for young children. However, when performance on theoretically related number tasks is taken into account, both the conventional and the modified N-P tasks appeared to underestimate competence.     

The Effect of Holy Qur’an Recitation on Depressive Symptoms in Hemodialysis Patients: A Randomized Clinical Trial

Patients with advanced renal failure often face considerable sociopsychological stress as a result of lifestyle changes due to the disease and its treatment. The aim of the present study is to examine the effect of the Holy Qur’an recitation on depressive symptoms in hemodialysis patients. In this clinical trial, 54 hemodialysis patients were randomized to either an experimental (n = 27) or a control (n = 27) group. Patients completed the Beck Depression Inventory-II (BDI-II) at baseline and at 1 month after the intervention. Participants in the experimental group listened to recitation of the Holy Qur’an, while those in the control group received no intervention. The mean BDI-II score at baseline was 33.6 (±6.7) for the experimental group and 29.3 (±9.0) for the control group; at the end of treatment, BDI-II scores in the experimental and control groups were 14.5 (±4.8) and 31.6 (±9.2), respectively. Results from the repeated-measures general linear model controlling for baseline differences indicated a significant treatment effect (F = 9.30, p = 0.004, Cohen’s d = 0.85). Holy Qur’an recitation has a significant effect on lowering depressive symptoms in hemodialysis patients. Holy Qur’an recitation is an easy-to-implement and cost-effective strategy that may be used to supplement the treatment of depression in this setting in Iran.

     

THE PEN-BASED COMPUTER AS AN ALTERNATIVE PLATFORM FOR TEST ADMINISTRATION

Pen-based computers are similar to paper and pencil (P&P) tests in the method of responding, and thus, may more closely match paper and pencil administration in construct equivalence than keyboard-entry computers. A study was conducted comparing P&P, pen-based note-book computer, and keyboard-entry PC versions of two test batteries. Participants completed tests administered using different administration modes on separate days; construct equivalence was evaluated by comparing Day 1-Day 2 correlations across conditions. Although construct equivalence was found for the power tests, differences emerged for the speeded tests. For the pen-based computer, solid evidence of equivalence to P&P appeared for all but one of the speeded tests, whereas the keyboard PC showed borderline equivalence for only one of the three speeded tests. These findings suggested that the pen-entry computer may be more capable than the keyboard-entry computer in maintaining construct equivalence to P&P tests.     

Severity of Self-Reported Depression in Patients with a Schizoaffective Disorder

  To investigate the severity of self-reported depression in patients diagnosed with a schizoaffective disorder (SZA), the Beck Depression Inventory-II (BDI-II; Beck, Steer, & Brown, 1996) was administered to 75 patients with a SZA. For comparative purposes, the BDI-II was also administered to 75 patients with a major depressive disorder without psychotic features (MDD) who were matched to the SZA sample with respect to sex, being Caucasian, and age. The Cronbach coefficient αs of the BDI-II total scores for the patients with a SZA or a MDD were, respectively, .94 and .92. The mean BDI-II total score (M = 23.71, SD = 15.44) of the patients with a SZA was minimally lower than the mean BDI-II score (M = 28.73, SD = 12.46) of the patients with a MDD. The BDI-II was discussed as being useful for assessing self-reported depression in patients diagnosed with a SZA.     

IGT-Open: An open-source,computerized version of the Iowa Gambling Task

The Iowa Gambling Task (IGT) is commonly used to understand the processes involved in decision-making. Though the task was originally run without a computer, using a computerized version of the task has become typical. These computerized versions of the IGT are useful, because they can make the task more standardized across studies and allow for the task to be used in environments where a physical version of the task may be difficult or impossible to use (e.g., while collecting brain imaging data). Though these computerized versions of the IGT have been useful for experimentation, having multiple software implementations of the task could present reliability issues. We present an open-source software version of the Iowa Gambling Task (called IGT-Open) that allows for millisecond visual presentation accuracy and is freely available to be used and modified. This software has been used to collect data from human subjects and also has been used to run model-based simulations with computational process models developed to run in the ACT-R architecture.     

Managing antidepressants in primary care: physicians' treatment modifications

To examine antidepressant management practices in primary care, patients (N = 148) given an antidepressant for at least one month completed the Beck Depression Inventory (BDI-II), the Patient Health Questionnaire-9 (PHQ-9), and a demographic survey. Participants' mean age was 50.7 yr. and 80% were women. Patients' charts indicated whether physicians had made changes to prescribed antidepressants or dose either 6 wk. before or 6 wk. after study entry. For the 87% of participants whose depression status could be determined, 10% met dysthymic disorder criteria and only 33% had had a medication change in the previous month. Major depressive disorder occurred in 37% but only 18% had had a medication change. Co-existing dysthymic disorder and major depressive disorder were diagnosed in 34%, with 24% receiving a medication change. Participants not receiving a medication change had mean BDI-II scores indicating moderate depression. Lack of antidepressant adjustment suggests physicians may need to monitor depressive symptoms closely using protocols and prompts.     

Equivalence of Computerized and Standard Administration of the Piers-Harris Children's Self-Concept Scale

Two hundred seventy-nine 8- to 17-year-old children and adolescents were randomly assigned to complete paper-and-pencil or computer-administered versions of the Piers-Harris Children's Self-Concept Scale. The equivalence of these two administration modes was assessed by evaluating the comparability of scale means, variances, reliabilities, and validities. Results indicate that, of 27 comparisons, only 1 produced a statistically significant difference. We concluded that the computerized administration of the Piers-Harris scale did not affect its psychometric properties and that paper-and-pencil and computerized modes of testing for this questionnaire may be regarded as equivalent.     

Impaired specific autobiographical memory as a risk factor for posttraumatic stress after trauma

This study tested the proposal that impaired retrieval of specific autobiographical memories is a risk factor for psychological disturbance after trauma exposure. Trainee firefighters (N = 60) were assessed during training (before trauma exposure) on the Autobiographical Memory Test, Clinician Administered PTSD Scale, Beck Depression Inventory (BDI-II), and Traumatic Events Questionnaire. Participants were reassessed 4 years later (N = 46) on the Posttraumatic Diagnostic Scale and BDI-II. All participants had been exposed to multiple traumatic events, and 15% met criteria for posttraumatic stress disorder. Impaired retrieval of specific memories in response to positive cues prior to trauma exposure significantly predicted posttraumatic stress severity after trauma exposure. These findings provide initial evidence that impaired specific retrieval of memories may be a risk factor for posttraumatic stress.     

The differential aptitude test (language usage and spelling): A clinical study of a computerized form

As part of the Leicester/DHSS project on microcomputer-aided assessment, 103 subjects were tested and retested on standard and computerized versions of the Differential Aptitude Tests for Language Usage and Spelling (Forms S and T). Subjects were generally faster on the computerized versions than on the standard versions. On the Language Usage test, subjects scored significantly higher on the computerized than on the standard test. The correlations found between the standard and computerized versions were modest in comparison to the original test-retest reliabilities. It is concluded that these data argue against the claim that the current computerized versions of the tests are psychometrically parallel to the standard versions. This research, which was carried out when the authors were at the Department of Psychology, University of Leicester, was supported by the United Kingdom Department of Health and Social Security.     

The underlying structure of the Beck Depression Inventory II: A multidimensional scaling approach

The purpose of the present study was to confirm Beck’s six symptom categorization of depression through the most recent version of Beck Depression Inventory (BDI-II) by employing a confirmatory multidimensional scaling (MDS). This analysis indicates two independent dimensions in the BDI-II. The disturbance domain dimension relates to the domains wherein the disturbances occur, and validates Beck’s six symptom categorization dividing the items into disturbances in basic need-satisfaction, energy regulation, focused attention, regulation of emotion, motivation, and cognitive distortion in self-evaluation. The level of arousal dimension relates to how the disturbances are expressed, namely in an under-active, regular, or over-active manifestation. The MDS solution suggests 18 (6 × 3) symptom areas of depression, and may serve as a guide for constructing additional items.     

Usability and Utility of a Computerized Cognitive-Behavioral Self-Help Program for Public Speaking Anxiety

This study describes the use of a cognitive-behavioral computer-administered self-help program with minimal therapist contact for public speaking anxiety. Participants (N = 10) with social phobia, as measured by a structured clinical interview, completed the self-help program in an open clinical trial. The program was delivered via a CD-ROM during individual sessions at an outpatient clinic, including 4 sessions of psychoeducation/cognitive therapy and 4 sessions of exposure therapy using a virtual audience presented on a computer screen. A therapist was available in another room to answer questions and to debrief for up to 10 minutes after each session. Participants completed standardized self-report questionnaires assessing social anxiety at pretreatment, posttreatment, and 3-month follow-up. Participants also completed measures of computer usability. Results showed decreases on all self-report measures of social anxiety from pre- to posttreatment, which were maintained at follow-up (n = 8). Participants also reported that they were satisfied with treatment, that they felt improved after treatment, and that the computer program was user-friendly. This study provides preliminary evidence that a computer-administered cognitive-behavioral-based program that includes minimal therapist contact may reduce public speaking anxiety and suggests that further research with a controlled design is needed.     

An examination of racial bias in the Beck Depression Inventory-II

Historically, many psychological measures were developed and standardized based on a primarily Caucasian population. These tests are subsequently applied to minorities and may be inappropriate and possibly even pathologizing. The widely used Beck Depression Inventory-II (BDI-II) was initially standardized on a sample of Caucasian university students and its use with minorities has only recently been investigated. This study examined the possibility of racial bias in the BDI-II by comparing Caucasian and African American Midwestern university students. A hierarchical multiple regression compared the scores of the BDI-II with a similar measure of depression that is standardized for use with African Americans. There was no evidence of racial bias discovered in the BDI-II in this sample. Implications and future directions of research are discussed.     

L'avenir de l'approche par élaboration de règles

The goal of this study is the elaboration of a computerized diagnostic instrument based on Siegler's rule-assessment approach for assessing the acquisition of the probability quantification scheme in subjects aged 6–18 years. Three versions of the test were used. Version 1 was Siegler's original version (four types of problems and four rules). In version 2 five new rules were added; version 3 contained the five new rules plus eleven types of problems. Results show that version 1 allows the classification of only 50% of subjects; version 2, 60%; and version 3, 70%. Despite improved versions, some weaknesses remain, the most important one being that it is still impossible to evaluate intra-individual variability. Aware of these limits, Siegler has reassigned his model to a local model of problem solving, and suggests a developmental model of information processing inspired by a Darwinian model of variation and strategy selection. The authors hypothesize that computer engineering could not only reaffirm the general status of the rule-assessment approach, but could also allow consideration of intra-individual variability.
