The topic controlled vocabulary is a list of the topic areas covered by the studies. It is a compilation of items from the MeSH and HASSET topic vocabularies. The topic vocabulary has two levels. Level 2 topics are subsets of the Level 1 topics.

CLOSER Discovery maps each question and each variable to a topic (see how to Apply topics for more details). This allows you to refine your search results using the topic you are interested in or browse questions and variables with a particular topic using the explore function.  

The table below provides descriptions of each of the topics and shows the relationship between the level 1 and level 2 topics. The description also includes source of the definition which have been taken from MeSH, HASSET, Oxford online, WHO, ONS, National Academy on Women's Health Medical Education, U.S. National Library of Medicine, Urdang (1988), Webster (1961), Stedman (1995) and Timmreck (1987).

Attitudes determine whether people like or dislike things – and therefore how they behave towards them. Attitude is traditionally divided into cognitive, behavioural, and affective components, although the main emphasis now tends to fall on defining attitude in terms of affect – the person's feelings towards the object, brand, etc. Is the brand good or bad?

The parent supports the child by exercising authority and through consistent, empathic, appropriate behavior in response to the child's needs. PARENTING differs from CHILD REARING in that in child rearing the emphasis is on the act of training or bringing up the children and the interaction between the parent and child, while parenting emphasizes the responsibility and qualities of exemplary behaviour of the parent.
