Reliability data for a Greek translation of the Revised UCLA Loneliness Scale: comparisons with data from the USA.

A Greek translation of the Revised UCLA Loneliness Scale was internally reliable (alpha = .89), after eliminating Item 4, and significantly correlated with the English version (r = .94) for a sample of bilingual students. Weiss's distinction between social loneliness and emotional loneliness was also reliably identified in the Greek translation. Loneliness scores in Greece were significantly higher than in the USA. The translation seems to be sufficiently reliable to warrant further use with Greek individuals.

Test-retest reliability of the Revised Self-monitoring Scale over a two-year period.

The Revised Self-monitoring Scale of Lennox and Wolfe was administered to 83 staff nurses in 1987 and in 1989 as part of on-going research. Test-retest correlations were: for Factor A, Ability to Modify Self-presentation, .53, for Factor B, Sensitivity to the Expressive Behavior of Others, .52, and for the Total Self-monitoring Score .55. These scores were sufficiently strong to warrant continued, but cautious use of this revised test.

Once daily therapy for streptococcal pharyngitis with cefadroxil.

To determine if a single daily dose of cefadroxil would be effective in the treatment of group A beta-hemolytic streptococcal (GABHS) pharyngitis, 196 patients with GABHS pharyngitis were randomly assigned to receive either penicillin V 250 mg three times daily or cefadroxil 30 mg/kg once daily, for 10 days. Outcome was measured by the ability to isolate GABHS from the upper respiratory tract 18 to 24 hours after the onset of therapy, the impact on the clinical course, and the bacteriologic treatment failure rate. There was no significant difference in the number of patients in the cefadroxil and penicillin V treatment groups with throat cultures positive for GABHS at the 18 to 24-hour follow-up visit (0% and 2%, respectively), and the clinical responses of the patients in the two treatment groups were similar. Of the 99 patients in the three times daily penicillin V group, six (6%) had strains of GABHS isolated on one of the follow-up cultures that were identical to the strains isolated from their initial throat cultures and were considered to have bacteriologic treatment failures. Of the 96 patients in the once daily cefadroxil group, two (2%) were considered to have bacteriologic treatment failures. A single daily dose of cefadroxil appears to be as effective in the treatment of GABHS pharyngitis in this population as penicillin V given three times daily.

Antigen detection test for streptococcal pharyngitis: evaluation of sensitivity with respect to true infections.

The clinical significance of false-negative results on antigen detection tests for group A beta-hemolytic streptococcal (GABHS) pharyngitis (negative test results and positive culture) has yet to be determined. We recently compared the Culturette Brand Ten-Minute Group A Strep ID Kit with blood agar cultures in 313 patients with pharyngitis, 257 (82%) of whom had positive throat cultures for GABHS. The Culturette Brand test had a sensitivity of 88%, specificity of 96%, a positive predictive value of 99%, and negative predictive value of 64%. More than half of the false-negative Culturette Brand test results occurred in children with less than 10 GABHS colonies on throat culture (1+ culture). When these 1+ cultures were not considered positive, the sensitivity of the Culturette Brand test was 93%. The sensitivity of the Culturette Brand test increased with an increased degree of positivity of the corresponding throat culture. Of the 31 children with false-negative Culturette Brand test results, 14 (45%) had a significant streptococcal antibody response; of the 224 children with true-positive Culturette Brand test results (positive test results and positive culture) from whom serologic data were available, 114 (51%) had a significant streptococcal antibody response. This difference is not statistically significant. These findings suggest that almost half of patients with false-negative results on antigen detection tests for GABHS pharyngitis have true infections (positive culture and antibody rise) and are not merely streptococcal carriers.

Enhancement of leader power after election or appointment to undersirable leader roles.

Sixteen groups of male and female university students (N= 129) were tested in a 2 by 2 design which varied mode of leader selection (election vs. appointment) and desirability of leader role (desirable vs. undersiable). Desirable leader roles were created by offering $5.00 and extra experimental credit for extra work to be completed on the leader's own time. Leaders in undersirable roles had to complete the extra work without pay or experimental credit. After a warm-up task, a confederate was either elected or appointed leader. On two subsequent tasks the leader made three influence attempts on (a) the task structure, (b) the task content, and (c) the members' willingness to volunteer to help the leader with the extra work. Results indicated that on all influence measures individuals elected to the undersirable leader role had significantly greater social power than individuals elected to the desirable role. Desirability of the leader role did not significantly affect the social power of appointed leaders.

Standardization of the physical therapy record.

The question of where to begin the assessment of quality care in physical therapy is examined. A standardized format to enhance patient-care record is presented, and the reasons for a systematized approach to recording patient care are explained.
