Assessing family involvement in traumatic brain injury rehabilitation: the development of a new instrument.

A measure for assessing family involvement in traumatic brain injury rehabilitation (TBI) was developed. The Family Involvement Assessment Scale (FIAS) is theoretically based on Barrer's (1988) model of family involvement in TBI rehabilitation, which highlights two dimensions, "support" and "involvement." An initial pool of 337 items believed to be related to the constructs of "support" and "involvement" was generated. Forty-nine items were systematically selected from the initial pool and included in a preliminary assessment form in which 172 professionals rated the items on the dimensions of support and involvement. Eleven items were subsequently eliminated from the original pool based on these ratings. The remaining 38 items were used by 181 of the professionals to evaluate the involvement of actual family members of patients receiving TBI rehabilitation services in their programs. A factor analysis was performed on a remaining pool of 38 items. Three factors with an eigenvalue greater than 2.0 accounted for 48.8% of the total variance. One item that did not significantly load on any of the factors was eliminated. The FIAS includes a final set of 37 items, comprised of three subscales based on the factor analysis. Two of the scales, the Involvement-Rehabilitation (IR) scale and the Support (S) scale correspond, respectively, to Barrer's (1988) dimensions of "involvement" and "support." The third scale, Involvement-Patient (IP), is a unique construct that measures the degree to which a family member is involved in the rehabilitation process with respect to their involvement and relationship with the patient. The three scales yielded adequate internal reliabilities. Correlation coefficients between the scales indicated that the IR and S scale are not statistically related, but the IP scale is significantly related to both the IR and S scales. Interrater and test-retest reliability, and concurrent and predictive validity for the FIAS are still to be determined.

More on volitional experiences and breaching posthypnotic amnesia.

3 experimental conditions using a mock lie detector were employed to investigate further the type of manipulations that lead posthynotically amnesic Ss to breach their amnesia before the reversibility cue is given. 1 condition told Ss they were telling the truth, another that they were lying, and another only that the physiological apparatus could tell whether they were telling the truth. Ss in the "lie" condition breached more than Ss in the other 2 conditions, which did not differ. Ss who rated their recall as in their control (voluntary) were more likely to report more material after breaching manipulations than Ss who reported their recall as not in their control (involuntary). The results are discussed as they relate to breaching conditions and the voluntary/involuntary dimension.

Neuropsychological deficits in active licensed professional boxers.

Young, active, licensed professional boxers (N = 19) were found to display a pattern of neuropsychological deficits consistent with the more severe punch-drunk syndrome of years past. These deficits resulted in significantly lower test performance than that of control athletes (N = 10) matched for race, age, and level of education. Tests that showed significant differences between groups include subtests of the Quick Neurological Screening Test, subtests of the Halstead-Reitan Neuropsychological Test Battery, and the Randt Memory Test. Fifteen of the 19 boxers scored in the impaired range of the Reitan Impairment Index, as compared to 2 of the 10 controls.

A physiological investigation of volitional and nonvolitional experience during posthypnotic amnesia.

Highly responsive hypnotic subjects, who were classified as having control over remembering (voluntaries) or not having control over remembering (involuntaries) during posthypnotic amnesia, were compared with each other on four physiological measures (heart rate, electrodermal response, respiration rate, muscle tension) during posthypnotic recall. Two contextual conditions were employed: One was meant to create pressure to breach posthypnotic amnesia (lie detector instructions); the other, a relax condition, served as a control. The recall data confirmed earlier findings of Howard and Coe and showed that voluntary subjects under the lie detector condition recalled more than the other three samples that did not differ from each other. However, using another measure of voluntariness showed that both voluntary and involuntary subjects breached under lie detector conditions. Electrodermal response supported the subjects' reports of control in this case. Physiological measures were otherwise insignificant. The results are discussed as they relate to (a) studies attempting to breach posthypnotic amnesia, (b) the voluntary/involuntary classification of subjects, and (c) theories of hypnosis.
