lsd (lysergic acid diethylamide) is a powerful bio-active substance related to serotonin in structure. Its actions generally affect autonomic, sensory and psychological functions. Autonomic stimulation is varied. Sensory responses are usually visual, involving heightened and distorted color perception and fusion of sensory impressions. Psychological responses include a feeling that a unique experience is occurring; feelings of depersonalization; pronounced fluctuation of mood; time and space distortions; autistic phenomena; fluctuation of aggressive drives (usually reduction); and spontaneous reoccurrence of the lsd experience. THE SUBJECTIVE RESPONSES CAN BE RELATED TO THREE BASIC PHENOMENA: (1) expectation; (2) loss of characteristic modes of perceptual and cognitive patterning; and (3) hypersuggestibility. THE MAJOR ADVERSE REACTIONS ARE: (1) chronic drug dependence including subsequent personality changes and depressive reactions; and (2) acute ego dissolution. These reactions usually occur in already emotionally ill people. Most of these users fall into two groups, those with unresolved identity problems and those with severe ego abnormality. The majority of adverse reactions are of the chronic drug dependence type and are usually seen in adolescents and young adults who have not negotiated the age-appropriate tasks of forming and integrating the various identities that are the composite of their life experiences.lsd helps alleviate these stresses via some of its psychological properties as discussed. It also provides a nidus for the formation of a subculture where goals for social, sexual and vocational achievement are lower and idiosyncratic modes of adaptation are better tolerated. A smaller group of users who have serious reactions such as psychosis, rage reactions, homicidal and suicidal ideation are usually found to have preexisting ego abnormality such as ambulatory schizophrenia, chronic impulse disorders and borderline states. Although adverse reactions most often appear to be related to pre-morbid psychopathology, this is not invariably so. Further, there is as yet no reliable method to determine who will have an adverse reaction and what the nature of that reaction will be.

Need for care was studied in a Dutch incidence cohort of patients with schizophrenic disorders 15 and 17 years from first onset of psychosis. Long-term course of the disorders varied from complete remission and full community participation to chronic psychosis and long-term hospital stay. Fifty patients were assessed twice with the Needs For Care Assessment Schedule (NFCAS, Brewin and Wing 1989); at the latter follow-up an assessment was also made using the Camberwell Assessment of Need (CAN, Phelan et al. 1995). The NFCAS is an investigator- or professional-based instrument which provides an 'objective' assessment of needs. Need for care was recorded in 22 areas of clinical and social functioning. Comparison of the two assessments over a 2-year period demonstrated a high stability on the individual items (mean 88%, mostly concerning the absence of a problem twice), but did not show the expected stability of need status among this group of patients with chronic disorders. One in five patients (22%) had no needs at all on both occasions and 56% of the patients showed a change in needs. There was more negative than positive change: 28% suffered from new unmet needs at the 17-year follow-up, while only 12% had improved their status to no needs. About one-third (36%) had at least one unmet need, mostly regarding psychotic symptoms, dyskinesia or underactivity. The CAN provides a 'subjective' assessment of needs according to the view of patients themselves. The problems patients reported most commonly were in the areas of day-time activities, social relationships and information on their condition and treatment, for all which they asked for more help than they received. This patient-based instrument produces slightly higher numbers of problems and unmet needs, and a lower ratio between met and unmet needs. There is an overall percentage of 21% of disagreement between patient and investigator view regarding the unmet need status. Agreement between the two instruments on the nature of the problems with unmet needs was lacking altogether.

The present study is a 5-year follow-up of patients with schizophrenia who were in-patients for more than 3 months in 1993. In all, 19 patients fulfilled the criteria and were interviewed 6 months after their discharge. Seventeen of them also participated in a follow-up 5 years later. Their needs were independently rated by themselves and by their key workers according to the Camberwell Assessment of Need (CAN, research version 3.0). The interview with the patients also included quality of life assessed by the Quality of Life Scale (QLS-100). The results from CAN showed a difference when using a cut-off point for higher vs. lower problem at 10 needs. Using this cut-off point, five patients at the baseline and one at the follow-up had higher problems. The need ranking with key workers showed a correlation of rho = 0.68 at the baseline and rho = 0.74 at the follow-up. QLS-100 showed that the patient's total number of unsatisfied items were significantly higher (p = 0.01) at the baseline than at the follow-up. At the follow-up, full insight into their illness was shown by most of the patients. There are several possible explanations associated with the increased quality of life, e.g. less unsatisfied items among some patients and greater autonomy at the follow-up.

The Camberwell Assessment of Need (the CAN) is a widely used instrument in several countries to assess needs for the severely mentally ill. The instrument consists of ratings of needs made by patient and staff. This paper reports test-retest reliability for staff ratings in the Swedish version. Fifty-six patients, most of them with a diagnosis of schizophrenia, were interviewed by one person from the social services and by one from the psychiatric clinic. Afterwards the ratings were discussed and negotiated in order to arrive at one unanimous rating. The same procedure was replicated after 2-4 weeks. The intraclass correlation coefficient for the sum of needs was 0.93, and for the sum of unmet needs and met needs 0.80 for both. There were no means differences between the first and second rating. An analysis was also made of the test-retest scores of individual needs and subscales. The results in this study suggest that the summary scores of the CAN generally are reliable over time when using the method applied here. General conclusions about test-retest reliability for individual needs and subscales are more difficult to make and demand larger samples.
