Sql COUNT em cada linha

Olá,

eu tenho uma sql para mostrar as respostas de 75 questoes de um questionario socio economico..

as pessoas respondem o questionario e salva no banco como na imagem abaixo:

e eu tenho uma query que mostra as perguntas com suas respostas...

mas quando mostro a qntde de respostas da coluna 'sim', por exemplo, ela repete o sql count, nao mostra qntas respostas teve cada pergunta!

Vou colocar o sql para vcs ver:

SELECT
(select count(*) from respostaaluno where sim=1 and IdPergunta=IdPergunta) as qtdSim,
(select count(*) from respostaaluno where nao=1 and nao is not null) as qtdNao,
(select count(*) from respostaaluno where nar=1 and nar is not null) as qtdNar,
(select count(*) from respostaaluno where i=1 and i is not null) as qtdI,
(select count(*) from respostaaluno where r=1 and r is not null) as qtdR,
(select count(*) from respostaaluno where b=1 and b is not null) as qtdB,
(select count(*) from respostaaluno where o=1 and o is not null) as qtdO,
(select count(*) from respostaaluno where e=1 and e is not null) as qtdE,
(select count(*) from respostaaluno where re=1 and re is not null) as qtdRe,
(select count(*) from respostaaluno where ru=1 and ru is not null) as qtdRu,
(select count(*) from respostaaluno where sempre=1 and sempre is not null) as qtdSempre,
(select count(*) from respostaaluno where asvezes=1 and asvezes is not null) as qtdAsvezes,
(select count(*) from respostaaluno where raramente=1 and raramente is not null) as qtdRaramente,
(select count(*) from respostaaluno where nunca=1 and nunca is not null) as qtdNunca

FROM respostaaluno GROUP BY IdPergunta

Não sei o que está errado, alguem tem uma solução??

Obrigado.
