Factor structure and reliability of the Reasons for Living Inventory.

This study examined the factor structure and internal consistency reliability of the Reasons for Living Inventory for 275 college students. Principal components factor analysis with varimax rotation extracted five factors, based on the scree test. The derived factors were identical with the inventory's subscales, except for the Fear of Suicide subscale and Social Disapproval subscale items loading on the same factor. Significant gender differences were obtained on the Responsibility to Family, the Fear of Suicide, and the Moral Objections subscales. The pattern of subscale correlations was similar for the subsamples. The coefficients alpha for the subscales ranged from moderate to high.

The relative efficacy of vestibular-proprioceptive stimulation and the upright position in enhancing visual pursuit in neonates.

48 healthy neonates born to multiparae were randomly assigned to view a moving stimulus either in the horizontal or the upright position, with or without added vestibular stimulation and with or without pacifier sucking. The infant was shown a moving black line inside a strictly controlled visual environment provided by an apparatus which permitted horizontal and upright positioning and displacement of the infant. Visual tracking was recorded by a concealed TV camera positioned at a constant distance and angle from the infants' eyes in both positions. Quality of tracking during each of 4 trials was scored on a 7-point scale. Results indicate that vestibularproprioceptive stimulation provided to the infant either horizontally or semivertically significantly enhanced his visual tracking, whereas the upright position did not. Pacifier sucking also improved his performace.
