A comparison of four computer-based telephone interviewing methods: Getting answers to sensitive questions

Interactive voice response (IVR) technology presents a new and promising approach by which to collect accurate data on sensitive topics by telephone interviews. In a national survey of 2, 880 households of alcohol and drug consumption, we compared computer-assisted telephone interviewing (CATI) and IVR with two hybrid methods that combine IVR with CATI. The principal hypothesis was that the self-report rates of sensitive behaviors would be higher for the hybrid and IVR methods owing to greater perceived confidentiality than with CATI. All the methods obtained similar sample demographic compositions. Response rates did not differ significantly between the CATI and the hybrid methods; however, the response rate with IVR was significantly lower. The hybrid and IVR methods obtained significantly higher self-report consumption rates for alcohol and marijuana and significantly higher hazardous drinking scores, as measured by the Alcohol Use Disorders Identification Test (AUDIT).

CATI provides (1) schedule design assistance, (2) new interviewing capabilities and controls which eliminate procedural errors, (3) coding assistance, (4) sampling administration, (5) interview supervision, and (6) postinterview data processing.     

Apple II/FIRST system control of electrical brain stimulation in the rabbit

An Apple II/FIRST system has been developed to control classical conditioning experiments, collect analog data, and extract dependent variable measures of conditioning from uniphasic (Scandrett & Gormezano, 1980) and multiphasic (Johnson, 1981) response signals. The present paper details the development of an electrical brain stimulation system as a peripheral device to the Apple II/FIRST system. In addition, data are presented that document the capabilities of the EBS system to concurrently stimulate up to eight animals while values along the dimension of each of four stimulation parameters are manipulated by a program written in FIRST. In our judgment, the EBS system has a number of advantages over currently available commercial stimulators, including cost, number of sites that can be independently stimulated, and availability of complete software control.     

A comparison of inexpensive statistical packages for apple II microcomputers

The purpose of this paper is to describe and compare some inexpensive software packages that calculate a variety of statistics on the Apple II microcomputer. For each package, hardware requirements, program capacity, limitations, constraints, accuracy, editing, error handling, and other features were studied.     

Some simple Apple II software for the collection and analysis of observational data

Two general-purpose software packages for collecting and analyzing observational data from a variety of settings are discussed. One package is designed for coding mutually exclusive behavioral states using the Apple’s keyboard as an input device. The other is designed to monitor temporally overlapping behaviors, and it makes use of the Apple II’s built-in game-control button inputs to indicate up to three behavioral states that may occur simultaneously.     

Microprocessor control and A/D data acquisition in classical conditioning

An Apple II/FIRST system has been developed to control classical conditioning experiments, collect analog data, and to extract dependent variable measures of conditioning. With our selection of the Apple II microprocessor and an added hardware floating-point processor, we have been able to establish independent computer systems for each of our three conditioning laboratories at a fraction of the cost of our DEC PDP-8/e (which was interfaced to only one of our laboratories). Moreover, our software system, FIRST, an interactive, high-level, dictionary-based language, is a programming and control system whose flexibility and ease of programming far exceeds that experienced with our DEC PDP-8/e system (Millenson, Kehoe, Tait, á Gormezano, 1973; Tait & Gormezano, 1974). In our judgment, the Apple II/FIRST system is of unprecedented efficiency and versatility for the control, data acquisition, and data analysis of analog responses in classical conditioning experiments.     

VIDEOLOGGER: A computerized multichannel event recorder for analyzing videotapes

A microcomputer-assisted system that permits multiple events to be coded from videotape to a common time base is described. The system allows an operator, by pressing a button, to record the onset and offset times of any number of events. It requires a video recorder, an Apple II microcomputer, a John Bell 6522 timing card, and a pair of switches. The software package consists of five programs: one to make timing signals on the videotape, one to record the onset time and duration of the operator’s buttonpresses, one to read and print the coding data from disk, one to operate the timer, and one to process the compiled code used in the software package. All necessary wiring diagrams are shown. Software is available gratis from the authors on request.     

Using an Apple II microcomputer for real-time control in a behavioral laboratory

This report describes the hardware and software developed to implement an Apple II (48 KB) as a real-time control device for operant experiments. The hardware has a straightforward design, so that it is readily understandable and can be built by individuals with only minimal experience in the use of integrated circuits and other electronic components. The software routines listed below represent an approach to controlling and handling the data generated by an operant experiment. Using these routines, we are able to record each response and experimental event, the time of the occurrence, and the conditions at that time.     

Two-Timing: Politics and Response Latencies in a Bilingual Survey

Through the recording of response times in a national four-wave bilingual panel survey, this study reports improvements in the prediction of vote choice up to 1 year in advance of a federal election. These results were achieved with conventional computer-assisted telephone interviewing (CATI) software, indicating that the immediate use of response time measures isboth practical and attractive for commercial as well as academic survey units. Even so, response latencies were found to be sensitive to political circumstance, such that timings should be analyzed separately for minority and majority populations. Moreover, a broad analytic focus, beyond timing only vote intention and partisan commitment, is recommended because latency data on core questions of identity and allegiance reveal a great deal about the contours ofpolitical context.     

Reliability and validity of the Coolidge Axis II Inventory: a new inventory for the assessment of personality disorders.

This group of studies describes the development of a 200 item, self-report, 4-point true-false inventory (Coolidge Axis II Inventory [CATI]) to assess personality disorders according to the criteria established in the Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev. [DSM-III-R]; American Psychiatric Association, 1987). The 13 personality disorder scales of the CATI had a mean test-retest reliability of .90 and a median internal consistency (Cronbach's alpha) of .76. There was a 50% concordance rate with clinician's diagnosis for 24 personality disordered patients. The median concurrent validity (raw score sums) between the CATI and the Millon Clinical Multiaxial Inventory-II for the 13 personality disorder scales was .58. Preliminary studies also support the reliability and validity of Depression, Anxiety, and Brain Dysfunction scales.     

Voice recognition with the Apple-Psych system

Use of the IntroVoice I voice recognition board with the Apple-Psych system is described. The device augments the EF ROM, keyboard ROM, and keyboard encoder chip in Apple II series computers and provides speaker-dependent recognition of up to 80 words. IntroVoice II, an upgrade, can recognize up to 160 words. Since the operation of IntroVoice is software-transparent, the Apple-Psych system recognizes the board’s output as console (keyboard) input, making it useful as a response collection device. The keyboard continues to operate normally, in parallel with voice recognition. Problems and solutions for response recognition and timing are discussed, and illustrative experimental data are presented.     

What is Apple-Psych?

Apple Psych, a system of software subroutines written in Apple Pascal and 6502 assembly language, was designed to run real-time psychological experiments on the Apple II, II+, and IIe microcomputers. This paper describes the minimum system requirements necessary to run Apple-Psych, the capabilities of the basic system, and the advantages and disadvantages of using Apple-Psych. Because the utility of a system to a researcher is often linked to its flexibility and expandability, this paper includes a brief discussion of hardware expansions already supported by the Apple Psych software and hardware expansions that would require additional software support.     

A split-screen electronic messaging system for Apple II computers

A method is described for configuring an Apple II+ or Apple IIe computer to create a multiuser, multiwindowed, electronic messaging system for use in computer-mediated communication research.     

Screen blanking on the Apple IIe

Screen blanking on the Apple IIe can be controlled by software after an annunciator output is connected to the chip enable line (Pin 18) of the character generator (UF4). Using Annunciator 3 gives the same functional results with the Apple IIe as does Reed’s (1979) hardware modification for the Apple II and Apple II+.     

The analysis of multiphasic signals with the Apple II/FIRST microprocessor system

An Apple II/FIRST system has been developed to control classical conditioning experiments, collect analog data, and extract dependent variable measures of conditioning from uniphasic response signals (Scandrett & Gormezano, 1980). The present paper covers an expansion in the capabilities of the system by the development of a multiphasic signal analysis algorithm written in FIRST, an interactive, high-level, dictionary-based language. The program provides unprecedented efficiency, sensitivity, and flexibility in the analysis of multiphasic analog response signals in classical conditioning experiments. Moreover, the program has the potential to analyze even more complex signal patterns.     

An experimental psychology laboratory system for the Apple II microcomputer

A system for on-line control of experiments is described that uses the Apple II microcomputer and requires no knowledge of programming. This system, APT, is used to construct test files, randomize stimulus order, and conduct experiments. Construction of an experiment is very easy through use of an interactive program. APT provides powerful options for controlling stimulus duration, feedback, and response type. Programs are available to conduct either a sequence of tests without any experimenter present or a single experiment. Over 200 subjects, ranging from 18 to 86 years of age, have completed a battery of cognitive and abilities tests using the system.     

A computer-controlled laboratory for studying infant event perception

An integrated software package for testing infants in a habituation procedure is described. The software is written for an Apple II computer with a minimum of 64K of memory. Additional interface cards are required for timing responses and displaying dynamic stimuli. The software is divided into four independent modules: (1) Configure Experiment allows the experimenter to design a specific experiment. (2) Run Experiment controls the running of a previously configured habituation experiment. (3) Calculate Reliability allows a second observer to score the subject for the purpose of computing reliability. (4) Data Summary and Formatting provides a summary of the results and allows the user to flexibly format the data for reading by various statistical packages.
