MICS Dictionary and Forms

Questionnaire Types

• There are four types of questionnaires:– Household– Women (age 15 - 49)– Children (age 0 - 4)– Men (age 15 – 49)


Identification Items

Questionnaire Cluster Number

Household Number

Line Number

Household HH1 HH2

Women HH1 HH2 LN

Under-fives HH1 HH2 LN

Men HH1 HH2 LN


Module Naming Conventions

• Each questionnaire module corresponds to a dictionary record

• A record’s name is MODXX, where XX is the module’s code/abbreviation; for example,– MODWS = Water and Sanitation Module

– MODCM = Child Mortality Module


Repeating Modules

• There are five (six) repeating modules:– Household listing

– Education

– Insecticide-treated nets

– Child labour

– Female genital cutting

– Birth history

• They are stored as repeating records


Dictionary Item Naming Conventions

• Dictionary items are named for– Their module– Their number

• Question 3 in the HL module is named– HL3

• The next slide describes the exception to this rule


Source and Response Questions

• A few questions have two parts– 1st part is the source of the response– 2nd part is the response

• Questions stored in two variables– Source has letter A as a suffix

• For example, question 4 in the AN module– AN4A – lying or standing up– AN4 – height


Dictionary Subitems• CSPro allows you to redefine an item into subitems

• Therefore, a subitem is a portion of an item

• To visually see the impact of this, press <ctrl+L>

• We make extensive use of subitems

• Both the item and the subitem can be referenced in an application; however, if we’ve created a subitem, that’s normally what we’ll use

• The situations in which we use them are described in the next four slides


Multiple Response Questions• Interviewer can circle more than one code• These variables are stored as alphanumeric variables

whose width is the total possible number of responses• There are many multiple response questions, e.g.,

MN2• In addition, for each possible response there is a

corresponding subitem whose name is the variable’s name + the response code

• For example, the six possible responses (A, B, C, F, G, X) to MN2 are stored in subitems MN2A, MN2B, MN4C, MN2F, MN2G and MN2X.


Date Variables (D/M/Y)• Date fields with several parts (e.g., day,

month, and year) are stored in one variable

• The variable has a subitem for each part of the date

• The subitems are named using the module, question number, and D, M, or Y– e.g., the day of household interview is stored

in subitem HH5D


Unit and Number Variables (U/N)

• A few questions have two parts where the– 1st part is the form of the response (i.e., the units)– 2nd part is the response (i.e., the number)

• These responses are stored in one item, split into two subitems, which have U and N suffixed to their names

• Example: question MN25 has– MN25U: time in hours or days, months (1 digit)– MN25N: number of hours or days (2 digits)


Level and Grade Variables (A/B)

• In the ED module, three questions record level and grade

• Stored in an item with two subitems– Level subitem has A suffix– Grade subitem has B suffix

• Example: question 4 of ED module– ED4A - highest level (1 digit)– ED4B - highest grade at that level (2 digits)


Coding Conventions

Response 1-digit 2-digit 3-digit 4-digit Alpha

Other 6 96 996 9996 X

Inconsistent 7 97 997 9997 -

Don’t Know 8 98 998 9998 Z

Missing 9 99 999 9999 ?

No one/None - - - - Y


Dictionary and Form Modifications

• Work on the Form File!• Add/remove modules and items to dictionary• Modify item characteristics if necessary

– e.g., item labels, lengths, and types; and value labels and ranges

• Update forms to reflect dictionary changes• Reorder flow of items (if items added)• Reposition items on the form (to match the flow)
