Introduction

The tables below summarise the measures used in the 9 Year study. Each measure is identified by the section heading and page number in the relevant booklet/questionnaire/score sheet, and by informal or formal names and descriptions. The number of items in each measure is shown, but note that some of these items have two or more parts, giving two or more item variables.

The final column of each table shows dataset scales that are related to each measure; each variable name here is a link that will take you to the relevant item in the 9 Year derived variables page.

Parent Booklet Measures

Refer to the parent booklet (pdf) for the section headings and page numbers referred to in this table.

Many of the measures in the parent booklet/interview are spread over several pages. Sometimes questions from different measures are interspersed with each other. Hence, the page numbers shown in the table below are often overlapping, and not in strict sequence.

The "number of items" shown is approximate. Some items have multiple parts. Where the same question is asked about each twin, this is only counted once in the number of items.
