Cognitive and psychosocial functioning of pediatric hematopoietic stem cell transplant patients: a prospective longitudinal study

A prospective longitudinal study of cognitive and psychosocial functioning in pediatric hematopoietic stem cell transplant (HSCT) patients was conducted on three occasions: pre-HSCT, 1 year post-HSCT, and 2 years post-HSCT. In contrast to the previous hypothesis that cognitive declines would occur as a result of HSCT treatment, it was hypothesized that (1) global cognitive functioning (IQ scores), as well as specific areas would remain stable over time; (2) pre-transplant functioning would be predictive of later functioning; and (3) age would be negatively related to cognitive functioning. Based on previous research it was further hypothesized: that (4) while declines in psychosocial functioning might be seen at 1 year, functioning would improve by 2 years. 153 children and adolescents were evaluated pre-HSCT and at 1 year, with 2 year data available for 74 children. Longitudinal analyses of Wechsler IQ data were completed on 100 children (longitudinal exact test) and 52 children (repeated measures analysis of variance. Results of cognitive assessment indicated (1) stability of IQ scores over time; and (2) that the strongest predictor was pre-HSCT cognitive functioning. Psychosocial assessment results indicated: (1) a low prevalence of behavioral and social problems; (2) stability in functioning over time; (3) pre-HSCT functioning strongly predictive of later functioning.

Pharmacologic and psychologic interventions for procedural pain

OBJECTIVE

This study evaluated a combined pharmacologic and psychologic intervention (combined intervention, CI) relative to a pharmacologic-only (PO) intervention in reducing child distress during invasive procedures in childhood leukemia. Predictors of child distress included age, group (CI, PO), and procedural variables (medications and doses, technical difficulty, number of needles required).

METHODOLOGY

This was a randomized, controlled prospective study that compared the PO (n = 45) and CI arms (n = 47), at 1, 6, and >12 months after diagnosis. A cross-sectional control group consisted of parents of 70 patients in first remission before the prospective study. Parent questionnaires, staff and parent ratings, and data on medications administered, technical difficulty of the procedure, and needle insertions were obtained for each procedure. This article reports on the final data point for the project (>12 months).

RESULTS

Mothers and nurses reported lower levels of child distress in the CI than the PO group. The CI and PO groups showed lower levels of child and parent distress than the cross-sectional control group. Distress decreased throughout the time, and child age was inversely related to distress (younger children had more distress) regardless of group. Child distress was associated with staff perceptions of the technical difficulty of the procedure and with child age, but not with medications administered.

CONCLUSIONS

The data showed that pharmacologic and psychologic interventions for procedural distress were effective in reducing child and parent distress and support integration of the two approaches. Younger children experienced more distress and warranted additional consideration. Staff perceptions of the technical difficulty of procedures were complex and potentially helpful in designing intervention protocols.

Posttraumatic stress, family functioning, and social support in survivors of childhood leukemia and their mothers and fathers

Psychological sequelae are examined in 130 former childhood leukemia patients and 155 comparison participants and their parents. The major dependent variables are symptoms of anxiety and posttraumatic stress, family functioning, and social support. Multivariate analyses of covariance indicated significantly more posttraumatic stress symptoms in mothers and fathers of childhood leukemia survivors (p < .001) and no differences between survivors and peers. There were no significant group differences for family functioning or social support, although they were associated with anxiety and posttraumatic stress outcomes. Current child age, age at diagnosis, and months off treatment were not significantly correlated with outcome. These findings document the long-term impact of childhood cancer treatment on parents. The lack of significant differences for survivors argues for further attention to the relevance of posttraumatic stress disorder for childhood cancer survivors. The clinical implications are that psychological interventions are needed during and after cancer treatment.

A randomized controlled prospective outcome study of a psychological and pharmacological intervention protocol for procedural distress in pediatric leukemia

Evaluated distress during invasive procedures in childhood leukemia. Child and parent distress, assessed by questionnaires and ratings, were compared in two arms of a randomized, controlled prospective study, one a pharmacologic only (PO) (n = 45) and the other a combined pharmacologic and psychological intervention (Cl) (n = 47), at 1, 2, and 6 months after diagnosis. The cross-sectional control group (CC) consisted of parents of 70 patients in first remission prior to the prospective study. Mothers' and nurses' ratings of child distress indicated less child distress in the Cl group than the PO. When contrasted with the CC group, the Cl group showed lower levels of child distress. Data showed decreases over time in distress and concurrent improvements in quality of life and parenting stress and supported an inverse association between distress and child age.

The Perception of Procedures Questionnaire: psychometric properties of a brief parent report measure of procedural distress

Reported the reliability and validity of the Perception of Procedures Questionnaire (PPQ), a 19-item parent-report measure developed to assess child and parent distress related to lumbar punctures and bone marrow aspirates in the diagnosis and treatment of childhood cancer. PPQ data from 140 mothers and 96 fathers of children and adolescents with leukemia in a first remission were analyzed separately. Factor analyses yielded five factors for mothers and fathers: Parent Satisfaction; Child Distress: During; Child Distress: Before; Parent Distress; and Parent Involvement. Internal consistency (Cronbach's alpha) was high for the total score and the five factor scores as were interrater reliabilities between mothers and fathers. Validity was determined using the Parenting Stress Index-Short Form, the Pediatric Oncology Quality of Life Scale, and parent and nurse ratings during procedures. Factors 2 and 3, assessing child distress, show strong associations with the validation measures and support the distinction between distress before and during procedures. This developing scale is recommended for use in the assessment and evaluation of child and parent procedure-related distress in pediatric oncology.
