RESUMEN
This study examines children's conceptual understanding and factual knowledge of the causes of cancer. Using a standardized, developmentally based, semistructured interview (ASK [AIDS (acquired immunodeficiency syndrome) Survey for Kids]), 784 children (43% black, 38% white, and 18% Hispanic; 48% female) in kindergarten through sixth grade attending six public elementary/middle schools in New Haven, Connecticut, were asked open-ended questions about the causes of cancer and, for comparison, the causes of colds and AIDS. Responses were scored for level of conceptual understanding and coded for factual content and factual accuracy. The level of conceptual understanding for causality of cancer increased consistently as grade level increased. When comparisons were made among the illnesses, children's level of conceptual understanding was significantly lower for the causes of cancer than for the causes of colds (p < .0001), but not significantly different from that of AIDS. Although the single most frequent cause of cancer mentioned was cigarettes/smoking (24%), more than one in five students stated that casual contact or contagion was a cause of cancer. More children cited causal contact/contagion than cited the following factually accurate or logically contributory causes combined: poor diet, air/water pollution or overexposure to sun, alcohol, and old age. Slightly more than one half of students in kindergarten through sixth grade worried about getting cancer, and the vast majority (80%) knew that cancer could be fatal. Children have a less sophisticated conceptual understanding of cancer than of colds and a very limited factual knowledge base for cancer, and thus they have the capacity to increase both their understanding and knowledge. These results have implications for the creation of developmentally appropriate cancer prevention curricula for elementary school-age children.

Symptoms are the outward manifestations that allow children to identify and recognize illness; children's understanding of the symptoms of an illness may be directly related to their understanding of its cause or means of transmission. This study is the first empirical investigation of children's conceptual understanding and factual knowledge of the symptoms of AIDS. Children (N = 361; grades K to 6; 57% black, 24% Hispanic, 19% white; 52% female) attending four public schools in New Haven, Connecticut, were interviewed using a standardized semistructured interview (ASK, AIDS Survey for Kids) that included open-ended questions about the symptoms of AIDS and, for comparison, cancer and colds. Responses were scored for level of conceptual understanding and coded for factual content. For each illness, grade level was the variable most strongly correlated with symptomatology concept score (R = .42-.48, p < .0001) and contributed significantly (p < .0001) to the variance observed in concept score even after controlling for race, gender, verbal fluency, and socioeconomic status. The mean concept score was lower (p < .01) for symptomatology of AIDS (2.8 of possible 5) than for cancer (3.1) or colds (3.9). In addition, far more symptoms were named for colds than for either cancer or AIDS. Children who believed that HIV is spread via each of five potential means of transmission by casual contact were more likely (p < 01) to cite cold symptoms as symptoms of AIDS. We conclude that there exists a developmental progression in children's understanding of the symptomatology of AIDS. Children have a less sophisticated conceptual understanding and narrower factual knowledge base for AIDS than for colds and therefore have the capability to increase their understanding and knowledge about AIDS. Furthermore, improving children's understanding of the symptoms of AIDS may diminish misconceptions about transmission of HIV via casual contact.

OBJECTIVE: Several educational theorists have suggested that young children are unlikely to benefit from detailed instruction regarding AIDS prevention because of inherent developmental cognitive limitations. This study aims to determine whether AIDS education in the elementary grades can advance young children's understanding of this illness. METHODS: A randomized, controlled trial was used to measure the impact of a 3-week, multifaceted AIDS education program on conceptual understanding, factual knowledge, and fears about AIDS in 189 students in grades kindergarten through 6th. The ASK (AIDS Survey for Kids), a standardized, semistructured interview that measures conceptual understanding, factual information, and fears about AIDS, was administered before and after the intervention. RESULTS: Children in the intervention group, as compared to those in the control group, showed significant (P < .0001) gains in their level of understanding of the concepts of causality and prevention of AIDS. These results were unaffected by controlling for grade, gender, race, socioeconomic status, and verbal fluency. The gains in children's understanding of causality of AIDS represented at least 2 years' growth in the level of conceptual sophistication and persisted at a follow-up evaluation several months later. After the intervention, more children (P < .001) in the intervention group than in the control group accurately identified causes of AIDS in response to open-ended questions: germ/germ theory (41% vs 13%), mother-to-infant transmission (54% vs 15%), blood transmission (83% vs 40%), and sexual transmission (56% vs 30%). Fewer than half as many children in the intervention group responded incorrectly to each of five direct questions about transmission of HIV through casual contact. The intervention did not increase children's fears about the illness. CONCLUSIONS: A short, developmentally based, multifaceted AIDS education program in the elementary grades can advance children's conceptual understanding and factual knowledge about AIDS and decrease their misconceptions about casual contact as a means of acquiring the illness, without increasing their fears. Significant advances in conceptual understanding about AIDS can be achieved through direct educational interventions.

OBJECTIVES: The developmental process by which young children acquire an understanding of the concepts of causality, treatment, and prevention of illness as related to acquired immunodeficiency syndrome (AIDS) is poorly understood. Previous studies have focused on adolescent populations and have measured the facts that children seem to know rather than their understanding of relevant concepts. Such approaches are likely to overestimate the child's true level of understanding and obscure significant misconceptions. The aims of this project are to measure directly the level of understanding of the concepts of causality, treatment, and prevention of AIDS in healthy, elementary school children and to assess the sociodemographic variables associated with their conceptual understanding. METHODS: Using a new, developmentally based, semistructured interview protocol (ASK, AIDS Survey for Kids), 361 children (57% black, 24% Hispanic, 19% white) in kindergarten through sixth grade at four public schools in New Haven, CT were interviewed. Responses to questions about causality, treatment, and prevention were scored for each of three illnesses (AIDS, and for comparison, colds and cancer) based on the level of conceptual sophistication of the response, irrespective of its factual accuracy. RESULTS: Scores for each of the concepts were highly intercorrelated and were correlated most strongly with grade level (R = .31 to .50, P < .0001 for each of these correlations, with the exception of the treatment of AIDS). Gender, race, and socioeconomic status did not contribute significantly to the variance observed for any of the concept scores in a linear regression model. Over-all, children's level of understanding of causality was significantly less sophisticated for AIDS than for colds (P < .0001); their level of conceptual understanding for the causality of AIDS was not significantly different from that of cancer (P = .9). CONCLUSIONS: Children's understanding of causality, treatment, and prevention of AIDS, as measured by the ASK, follows the same developmental sequence reported for children's understanding of general physical illness. Sociodemographic variables, such as race, gender, and socioeconomic status do not affect children's level of sophistication of these developmental concepts. These results have implications for the creation of developmentally appropriate and effective AIDS education curricula for primary and elementary grades. They also offer guidance to health care providers in their efforts to educate parents and young children about this important topic.
